-+Overlay Filesystem
-+==================
-+
-+This document describes a prototype for a new approach to providing
-+overlay-filesystem functionality in Linux (sometimes referred to as
-+union-filesystems). An overlay-filesystem tries to present a
-+filesystem which is the result over overlaying one filesystem on top
-+of the other.
-+
-+The result will inevitably fail to look exactly like a normal
-+filesystem for various technical reasons. The expectation is that
-+many use cases will be able to ignore these differences.
-+
-+This approach is 'hybrid' because the objects that appear in the
-+filesystem do not all appear to belong to that filesystem. In many
-+cases an object accessed in the union will be indistinguishable
-+from accessing the corresponding object from the original filesystem.
-+This is most obvious from the 'st_dev' field returned by stat(2).
-+
-+While directories will report an st_dev from the overlay-filesystem,
-+all non-directory objects will report an st_dev from the lower or
-+upper filesystem that is providing the object. Similarly st_ino will
-+only be unique when combined with st_dev, and both of these can change
-+over the lifetime of a non-directory object. Many applications and
-+tools ignore these values and will not be affected.
-+
-+Upper and Lower
-+---------------
-+
-+An overlay filesystem combines two filesystems - an 'upper' filesystem
-+and a 'lower' filesystem. When a name exists in both filesystems, the
-+object in the 'upper' filesystem is visible while the object in the
-+'lower' filesystem is either hidden or, in the case of directories,
-+merged with the 'upper' object.
-+
-+It would be more correct to refer to an upper and lower 'directory
-+tree' rather than 'filesystem' as it is quite possible for both
-+directory trees to be in the same filesystem and there is no
-+requirement that the root of a filesystem be given for either upper or
-+lower.
-+
-+The lower filesystem can be any filesystem supported by Linux and does
-+not need to be writable. The lower filesystem can even be another
-+overlayfs. The upper filesystem will normally be writable and if it
-+is it must support the creation of trusted.* extended attributes, and
-+must provide valid d_type in readdir responses, at least for symbolic
-+links - so NFS is not suitable.
-+
-+A read-only overlay of two read-only filesystems may use any
-+filesystem type.
-+
-+Directories
-+-----------
-+
-+Overlaying mainly involved directories. If a given name appears in both
-+upper and lower filesystems and refers to a non-directory in either,
-+then the lower object is hidden - the name refers only to the upper
-+object.
-+
-+Where both upper and lower objects are directories, a merged directory
-+is formed.
-+
-+At mount time, the two directories given as mount options are combined
-+into a merged directory:
-+
-+ mount -t overlayfs overlayfs -olowerdir=/lower,upperdir=/upper /overlay
-+
-+Then whenever a lookup is requested in such a merged directory, the
-+lookup is performed in each actual directory and the combined result
-+is cached in the dentry belonging to the overlay filesystem. If both
-+actual lookups find directories, both are stored and a merged
-+directory is created, otherwise only one is stored: the upper if it
-+exists, else the lower.
-+
-+Only the lists of names from directories are merged. Other content
-+such as metadata and extended attributes are reported for the upper
-+directory only. These attributes of the lower directory are hidden.
-+
-+whiteouts and opaque directories
-+--------------------------------
-+
-+In order to support rm and rmdir without changing the lower
-+filesystem, an overlay filesystem needs to record in the upper filesystem
-+that files have been removed. This is done using whiteouts and opaque
-+directories (non-directories are always opaque).
-+
-+The overlay filesystem uses extended attributes with a
-+"trusted.overlay." prefix to record these details.
-+
-+A whiteout is created as a symbolic link with target
-+"(overlay-whiteout)" and with xattr "trusted.overlay.whiteout" set to "y".
-+When a whiteout is found in the upper level of a merged directory, any
-+matching name in the lower level is ignored, and the whiteout itself
-+is also hidden.
-+
-+A directory is made opaque by setting the xattr "trusted.overlay.opaque"
-+to "y". Where the upper filesystem contains an opaque directory, any
-+directory in the lower filesystem with the same name is ignored.
-+
-+readdir
-+-------
-+
-+When a 'readdir' request is made on a merged directory, the upper and
-+lower directories are each read and the name lists merged in the
-+obvious way (upper is read first, then lower - entries that already
-+exist are not re-added). This merged name list is cached in the
-+'struct file' and so remains as long as the file is kept open. If the
-+directory is opened and read by two processes at the same time, they
-+will each have separate caches. A seekdir to the start of the
-+directory (offset 0) followed by a readdir will cause the cache to be
-+discarded and rebuilt.
-+
-+This means that changes to the merged directory do not appear while a
-+directory is being read. This is unlikely to be noticed by many
-+programs.
-+
-+seek offsets are assigned sequentially when the directories are read.
-+Thus if
-+ - read part of a directory
-+ - remember an offset, and close the directory
-+ - re-open the directory some time later
-+ - seek to the remembered offset
-+
-+there may be little correlation between the old and new locations in
-+the list of filenames, particularly if anything has changed in the
-+directory.
-+
-+Readdir on directories that are not merged is simply handled by the
-+underlying directory (upper or lower).
-+
-+
-+Non-directories
-+---------------
-+
-+Objects that are not directories (files, symlinks, device-special
-+files etc.) are presented either from the upper or lower filesystem as
-+appropriate. When a file in the lower filesystem is accessed in a way
-+the requires write-access, such as opening for write access, changing
-+some metadata etc., the file is first copied from the lower filesystem
-+to the upper filesystem (copy_up). Note that creating a hard-link
-+also requires copy_up, though of course creation of a symlink does
-+not.
-+
-+The copy_up may turn out to be unnecessary, for example if the file is
-+opened for read-write but the data is not modified.
-+
-+The copy_up process first makes sure that the containing directory
-+exists in the upper filesystem - creating it and any parents as
-+necessary. It then creates the object with the same metadata (owner,
-+mode, mtime, symlink-target etc.) and then if the object is a file, the
-+data is copied from the lower to the upper filesystem. Finally any
-+extended attributes are copied up.
-+
-+Once the copy_up is complete, the overlay filesystem simply
-+provides direct access to the newly created file in the upper
-+filesystem - future operations on the file are barely noticed by the
-+overlay filesystem (though an operation on the name of the file such as
-+rename or unlink will of course be noticed and handled).
-+
-+
-+Non-standard behavior
-+---------------------
-+
-+The copy_up operation essentially creates a new, identical file and
-+moves it over to the old name. The new file may be on a different
-+filesystem, so both st_dev and st_ino of the file may change.
-+
-+Any open files referring to this inode will access the old data and
-+metadata. Similarly any file locks obtained before copy_up will not
-+apply to the copied up file.
-+
-+On a file is opened with O_RDONLY fchmod(2), fchown(2), futimesat(2)
-+and fsetxattr(2) will fail with EROFS.
-+
-+If a file with multiple hard links is copied up, then this will
-+"break" the link. Changes will not be propagated to other names
-+referring to the same inode.
-+
-+Symlinks in /proc/PID/ and /proc/PID/fd which point to a non-directory
-+object in overlayfs will not contain vaid absolute paths, only
-+relative paths leading up to the filesystem's root. This will be
-+fixed in the future.
-+
-+Some operations are not atomic, for example a crash during copy_up or
-+rename will leave the filesystem in an inconsitent state. This will
-+be addressed in the future.
-+
-+Changes to underlying filesystems
-+---------------------------------
-+
-+Offline changes, when the overlay is not mounted, are allowed to either
-+the upper or the lower trees.
-+
-+Changes to the underlying filesystems while part of a mounted overlay
-+filesystem are not allowed. If the underlying filesystem is changed,
-+the behavior of the overlay is undefined, though it will not result in
-+a crash or deadlock.

-Subject: MIPS: Add crash and kdump support
-
-From: http://patchwork.linux-mips.org/patch/1025/
-
-Hello folks,
-
-Please find here MIPS crash and kdump patches.
-This is patch set of 3 patches:
-1. generic MIPS changes (kernel);
-2. MIPS Cavium Octeon board kexec/kdump code (kernel);
-3. Kexec user space MIPS changes.
-
-Patches were tested on the latest linux-mips@ git kernel and the latest
-kexec-tools git on Cavium Octeon 50xx board.
-
-I also made the same code working on RMI XLR/XLS boards for both
-mips32 and mips64 kernels.
-
-Best regards,
-Maxim Uvarov.
-
-------
-[ Zhangjin: Several trivial building failure has been fixed.
-
-Note: the 2nd patch can not be cleanly applied, but may be a good
-reference for the other board development:
-
- + MIPS Cavium Octeon board kexec,kdump support
- http://patchwork.linux-mips.org/patch/1026/
-
-And the 3rd patch has already been merged into the mainline kexec-tools:
-
- + some kexec MIPS improvements
- http://patchwork.linux-mips.org/patch/1027/
-
-kexec-tools is available here:
-
- + http://horms.net/projects/kexec/
- git://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git
-]

-From: Wu Zhangjin <wuzhangjin@gmail.com>
-Date: Tue, 11 Jan 2011 18:42:08 +0000
-Subject: MIPS: Kexec: Enhance the support
-
-Changes:
- o Print more information in machine_kexec() for debugging
- E.g. with this information, the kexec_start_address has been found
- it was wrong with 64bit kernel / o32 kexec-tools. Which must be
- fixed later.
- o Link relocate_kernel.S to a section for future extension
- This allows more functions can be added for the kexec relocation
- part even written in C. to add code into that section, you just need
- to mark your function or data with __kexec or
- __attribute__((__section__(".__kexec.relocate")))
-
-TODO:
-
-1. Make 64bit kernel / o32|n32|64 kexec-tools works
-
-Fix the user-space kexec-tools, seems the tool only work for 32bit
-machine. So, we need to add 64bit support for it. The address of the
-entry point(kexec_start_address) is wrong and make the "kexec -e" fail.
-the real entry point must be read from the new kernel image by the
-user-space kexec-tools, otherwise, it will not work. The above 64bit
-support tested is 64bit kernel with o32 user-space kexec-tools. The root
-cause may be the different definition of virt_to_phys() and
-phys_to_virt() in the kexec-tools and kernel space for 64bit system /
-o32 kernel.
-
-Ref: http://www.linux-mips.org/archives/linux-mips/2009-08/msg00149.html
-
-2. Pass the arguments from kexec-tools to the new kernel image
-
-Please refer to: "MIPS: Loongson: Kexec: Pass parameters to new kernel"

-Subject: MIPS: Get kernel parameters from kexec-tools
-
-Before, we simply use the command lines from the original bootloader,
-but it is not convenient. Now, we accept the kernel parameters from the
---command-line or --append option of the kexec-tools. But If not
---command-line or --apend option indicated, will fall back to use the
-ones from the original bootloader.

-- is not needed. These Blocks are reserved per partition, so if
-- you have very small partitions the default (10) may be a mess

-+GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
-+================================================================
-+
-+The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
-+MMC or SD card on GPIO pins.
-+
-+Two interfaces for registering a new MMC/SD card device are provided:
-+A static platform-device based mechanism and a dynamic configfs based interface.
-+
-+
-+Registering devices via platform-device
-+=======================================
-+
-+The platform-device interface is used for registering MMC/SD devices that are
-+part of the hardware platform. This is most useful only for embedded machines
-+with MMC/SD devices statically connected to the platform GPIO bus.
-+
-+The data structures are declared in <linux/mmc/gpiommc.h>.
-+
-+To register a new device, define an instance of struct gpiommc_platform_data.
-+This structure holds any information about how the device is hooked up to the
-+GPIO pins and what hardware modes the device supports. See the docbook-style
-+documentation in the header file for more information on the struct fields.
-+
-+Then allocate a new instance of a platform device by doing:
-+
-+ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
-+
-+This will allocate the platform device data structures and hook it up to the
-+gpiommc driver.
-+Then add the gpiommc_platform_data to the platform device.
-+
-+ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
-+
-+You may free the local instance of struct gpiommc_platform_data now. (So the
-+struct may be allocated on the stack, too).
-+Now simply register the platform device.
-+
-+ err = platform_device_add(pdev);
-+
-+Done. The gpiommc probe routine will be invoked now and you should see a kernel
-+log message for the added device.
-+
-+
-+Registering devices via configfs
-+================================
-+
-+MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
-+selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
-+hardware are a common situation.
-+So we provide a dynamic interface to conveniently handle adding and removing
-+devices from userspace, without the need to recompile the kernel.
-+
-+The "gpiommc" subdirectory at the configfs mountpoint is used for handling
-+the dynamic configuration.
-+
-+To create a new device, it must first be allocated with mkdir.
-+The following command will allocate a device named "my_mmc":
-+ mkdir /config/gpiommc/my_mmc
-+
-+There are several configuration files available in the new
-+/config/gpiommc/my_mmc/ directory:
-+
-+gpio_data_in = The SPI data-IN GPIO pin number.
-+gpio_data_out = The SPI data-OUT GPIO pin number.
-+gpio_clock = The SPI Clock GPIO pin number.
-+gpio_chipselect = The SPI Chipselect GPIO pin number.
-+gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
-+ If 1, Chipselect is active-LOW.
-+spi_mode = The SPI data mode. Can be 0-3.
-+spi_delay = Enable all delays in the lowlevel bitbanging.
-+max_bus_speed = The maximum SPI bus speed. In Hertz.
-+
-+register = Not a configuration parameter.
-+ Used to register the configured card
-+ with the kernel.
-+
-+The device must first get configured and then registered by writing "1" to
-+the "register" file.
-+The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
-+and "gpio_chipselect" are essential and _must_ be configured before writing
-+"1" to the "register" file. The registration will fail, otherwise.
-+
-+The default values for the other parameters are:
-+gpio_chipselect_activelow = 1 (CS active-LOW)
-+spi_mode = 0 (SPI_MODE_0)
-+spi_delay = 1 (enabled)
-+max_bus_speed = 5000000 (5 Mhz)
-+
-+Configuration values can not be changed after registration. To unregister
-+the device, write a "0" to the "register" file. The configuration can be
-+changed again after unregistering.
-+
-+To completely remove the device, simply rmdir the directory
-+(/config/gpiommc/my_mmc in this example).
-+There's no need to first unregister the device before removing it. That will
-+be done automatically.

-Although the commit "98af057092f8f0dabe63c5df08adc2bbfbddb1d2
- ARM: 6126/1: ARM mpcore_wdt: fix build failure and other fixes"
-resolved long standing mpcore_wdt driver build problems, it
-introduced an error in the relationship between the MPcore watchdog
-timer clock rate and mpcore_margin, "MPcore timer margin in seconds",
-such that watchdog timeouts are now arbitrary rather than the number
-of seconds specified by mpcore_margin.
-
-This change restores mpcore_wdt_keepalive() to its equivalent
-implementation prior to commit 98af057 such that watchdog timeouts now
-occur as specified by mpcore_margin.
-
-The variable 'mpcore_timer_rate' which caused that build failure was
-replaced by 'twd_timer_rate'. Adding exported function to obtain
-'twd_timer_rate' value in mpcore_wdt driver.
-
-MPCORE_WATCHDOG needed to build 'mpcore_wdt' already depends on
-HAVE_ARM_TWD needed to build 'smp_twd', so from the point of view of
-'mpcore_wdt' driver the exported function will always exist.

-According to the include/linux/watchdog.h WDIOC_SETOPTIONS is
-classified as 'read from device' ioctl call:
- #define WDIOC_SETOPTIONS _IOR(WATCHDOG_IOCTL_BASE, 4, int)
-
-However, the driver 'mpcore_wdt' performs 'copy_from_user' only if
-_IOC_WRITE is set, thus the local variable 'uarg' which is used in
-WDIOC_SETOPTIONS handling remains uninitialized.
-
-The proper way to fix this is to bind WDIOC_SETOPTIONS to _IOW,
-but this will break compatibility.
-So adding additional condition for performing 'copy_from_user'.
