+    xfs: avoid false quotacheck after unclean shutdown
+    
+    The commit
+    
+    83e782e xfs: Remove incore use of XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD
+    
+    added a new function xfs_sb_quota_from_disk() which swaps
+    on-disk XFS_OQUOTA_* flags for in-core XFS_GQUOTA_* and XFS_PQUOTA_*
+    flags after the superblock is read.
+    
+    However, if log recovery is required, the superblock is read again,
+    and the modified in-core flags are re-read from disk, so we have
+    XFS_OQUOTA_* flags in memory again.  This causes the
+    XFS_QM_NEED_QUOTACHECK() test to be true, because the XFS_OQUOTA_CHKD
+    is still set, and not XFS_GQUOTA_CHKD or XFS_PQUOTA_CHKD.
+    
+    Change xfs_sb_from_disk to call xfs_sb_quota_from disk and always
+    convert the disk flags to in-memory flags.
+    
+    Add a lower-level function which can be called with "false" to
+    not convert the flags, so that the sb verifier can verify
+    exactly what was on disk, per Brian Foster's suggestion.
