Forced quotacheck after unclean unmount since 3.11, bisected

[Cyril B.]

Hello,

I've noticed that since Linux 3.11, quotacheck always happen after 
unclean unmounts. Is this expected? It didn't happen on previous Linux 
versions.

A bisect shows that this commit is responsible:
xfs: Remove incore use of XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD
id: 83e782e1a1cc0159888e58e14dfc8f3289663338

Relevant dmesg:

[    9.331785] XFS (md4): Ending recovery (logdev: internal)
