+Subject: [PATCH] configfs: Remove ppos increment in configfs_write_bin_file
+
+[ Back-port of f8608985f851c917b3884b692d8e326b0210d34e ]
+
+The simple_write_to_buffer() already increments the @ppos on success,
+see fs/libfs.c simple_write_to_buffer() comment:
+
+"
+On success, the number of bytes written is returned and the offset @ppos
+advanced by this number, or negative value is returned on error.
+"
+
+If the configfs_write_bin_file() is invoked with @count smaller than the
+total length of the written binary file, it will be invoked multiple times.
+Since configfs_write_bin_file() increments @ppos on success, after calling
+simple_write_to_buffer(), the @ppos is incremented twice.
+
+Subsequent invocation of configfs_write_bin_file() will result in the next
+piece of data being written to the offset twice as long as the length of
+the previous write, thus creating buffer with "holes" in it.
+
+The simple testcase using DTO follows:
+  $ mkdir /sys/kernel/config/device-tree/overlays/1
+  $ dd bs=1 if=foo.dtbo of=/sys/kernel/config/device-tree/overlays/1/dtbo
+Without this patch, the testcase will result in twice as big buffer in the
+kernel, which is then passed to the cfs_overlay_item_dtbo_write() .
