| Subject: f2fs: fix to recover inode's uid/gid during POR |
| |
| From: Chao Yu <yuchao0@huawei.com> |
| |
| [ Upstream commit dc4cd1257c86451cec3e8e352cc376348e4f4af4 ] |
| |
| Step to reproduce this bug: |
| 1. logon as root |
| 2. mount -t f2fs /dev/sdd /mnt; |
| 3. touch /mnt/file; |
| 4. chown system /mnt/file; chgrp system /mnt/file; |
| 5. xfs_io -f /mnt/file -c "fsync"; |
| 6. godown /mnt; |
| 7. umount /mnt; |
| 8. mount -t f2fs /dev/sdd /mnt; |
| |
| After step 8) we will expect file's uid/gid are all system, but during |
| recovery, these two fields were not been recovered, fix it. |
