Merge tag 'for-5.2-rc5-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave...

Pull btrfs fixes from David Sterba:

 - regression where properties stored as xattrs are not properly
   persisted

 - a small readahead fix (the fstests testcase for that fix hangs on
   unpatched kernel, so we'd like get it merged to ease future testing)

 - fix a race during block group creation and deletion
