From: Chao Yu <yuchao0@huawei.com>
[ Upstream commit 5cd1f387a13b5188b4edb4c834310302a85a6ea2 ]
Testcase to reproduce this bug: 1. mkfs.f2fs -O extra_attr -O inode_crtime /dev/sdd 2. mount -t f2fs /dev/sdd /mnt/f2fs 3. touch /mnt/f2fs/file 4. xfs_io -f /mnt/f2fs/file -c "fsync" 5. godown /mnt/f2fs 6. umount /mnt/f2fs 7. mount -t f2fs /dev/sdd /mnt/f2fs 8. xfs_io -f /mnt/f2fs/file -c "statx -r"
stat.btime.tv_sec = 0 stat.btime.tv_nsec = 0
This patch fixes to recover inode creation time fields during mount.
