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
