-Subject: [PATCH] UBI: make UBI_IOCVOLCRBLK take a parameter for future usage
-
-In order to allow a future ioctl parameter, such as a creation flag,
-we change the UBI_IOCVOLCRBLK so it accepts a struct ubi_blkcreate_req.
-For the time being the structure is not in use, but fully reserved.
-
-This ABI change is still possible and harmless, because the ioctl has just
-been introduced and there's no userspace program which uses it.
