Merge tag 'for-7.1-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs fixes from David Sterba:
 "A batch of fixes to simple quotas:

   - add conditional rescheduling point not dependent on the lock during
     inode iterations to avoid delays with PREEMPT_NONE enabled

   - fix subvolume deletion so it does not break the squota invariants

   - properly handle enabling squota, tracking extents in the initial
     transaction

   - catch and warn about underflows, clamp to zero to avoid further
     problems

  And one fix to inode size handling:

   - fix handling of preallocated extents beyond i_size when not using
     the no-holes feature"
