Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull quota interface unification and misc cleanups from Jan Kara: "The first part of the series unifying XFS and VFS quota interfaces. This part unifies turning quotas on and off so quota-tools and xfs_quota can be used to manage any filesystem. This is useful so that userspace doesn't have to distinguish which filesystem it is working with. As a result we can then easily reuse tests for project quotas in XFS for ext4. This also contains minor cleanups and fixes for udf, isofs, and ext3" * 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: (23 commits) udf: remove bool assignment to 0/1 udf: use bool for done quota: Store maximum space limit in bytes quota: Remove quota_on_meta callback ocfs2: Use generic helpers for quotaon and quotaoff ext4: Use generic helpers for quotaon and quotaoff quota: Add ->quota_{enable,disable} callbacks for VFS quotas quota: Wire up ->quota_{enable,disable} callbacks into Q_QUOTA{ON,OFF} quota: Split ->set_xstate callback into two xfs: Remove some pointless quota checks xfs: Remove some useless flags tests xfs: Remove useless test quota: Verify flags passed to Q_SETINFO quota: Cleanup flags definitions ocfs2: Move OLQF_CLEAN flag out of generic quota flags quota: Don't store flags for v2 quota format jbd: drop jbd_ENOSYS debug udf: destroy sbi mutex in put_super udf: Check length of extended attributes and allocation descriptors udf: Remove repeated loads blocksize ...
