The patch titled
FAT: DIO-write fallback to normal buffered
has been removed from the -mm tree. Its filename was
fat-dio-write-fallback-to-normal-buffered.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: FAT: DIO-write fallback to normal buffered
From: OGAWA Hirofumi <hirofumi@xxxxxxxxxxxxxxxxxx>
If the DIO write on FAT is expanding the size, it will be fail by -EINVAL,
because FAT can't handle it now.
This patch fallback it to the normal buffered-write and would return
success.
