[PATCH] xfs_repair: don't call xfs_sb_quota_from_disk twice
|
|
|
|
|
|
|
|
|
|
kernel commit 5ef828c4
|
|
|
|
|
xfs: avoid false quotacheck after unclean shutdown
|
|
|
|
|
|
|
|
|
|
made xfs_sb_from_disk() also call xfs_sb_quota_from_disk
|
|
|
|
|
by default.
|
|
|
|
|
|
|
|
|
|
However, when this was merged to libxfs, existing separate
|
|
|
|
|
calls to libxfs_sb_quota_from_disk remained, and calling it
|
|
|
|
|
twice in a row on a V4 superblock leads to issues, because:
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
if (sbp->sb_qflags & XFS_PQUOTA_ACCT) {
|
|
|
|
|
...
|
|
|
|
|
sbp->sb_pquotino = sbp->sb_gquotino;
|
|
|
|
|
sbp->sb_gquotino = NULLFSINO;
|
|
|
|
|
|
|
|
|
|
and after the second call, we have set both pquotino and gquotino
|
|
|
|
|
to NULLFSINO.
|
|
|
|
|
|
|
|
|
|
Fix this by making it safe to call twice, and also remove the extra
|
|
|
|
|
calls to libxfs_sb_quota_from_disk.
|
|
|
|
|
|
|
|
|
|
This is only spotted when running xfstests with "-m crc=0" because
|
|
|
|
|
the sb_from_disk change came about after V5 became default, and
|
|
|
|
|
the above behavior only exists on a V4 superblock.
