Subject: [PATCH 2/2] Fix limits setting on XFS filesystem

xfs_commit_dquot() always set FS_DQ_LIMIT_MASK when calling
|
|
|
d26b56 |
Q_XFS_SETQLIM. So far this wasn't a problem since quota tools didn't
|
|
|
d26b56 |
support setting of anything else for XFS but now that kernel will start
|
|
|
d26b56 |
supporting setting of grace times for XFS, we need to be more careful
|
|
|
d26b56 |
and set limits bits only if we really want to update them. Also
|
|
|
d26b56 |
FS_DQ_LIMIT_MASK contains real-time limits as well. Quota tools
|
|
|
d26b56 |
currently don't support them in any way so avoid telling kernel to set
|
|
|
d26b56 |
them.
