Hi Jaegeuk, isize AUTO_RECOVER still be corrupted..., try below case: 1. xfs_io -f /mnt/f2fs/file -c "pwrite 0 4096" -c "fsync" 2. xfs_io -f /mnt/f2fs/file -c "falloc -k 4096 4096" -c "fsync" 3. md5sum /mnt/f2fs/file; 4. godown /mnt/f2fs/ 5. umount /mnt/f2fs/ 6. mount -t f2fs /dev/sdx /mnt/f2fs 7. md5sum /mnt/f2fs/file It's hard to deside to recover isize or not when current recovered block is fallocated, as we can allocate block inside or outside of isize. Any thoughts?

If i_size is not aligned to the f2fs's block size, we should not skip inode update during fsync. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> --- fs/f2fs/f2fs.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
