[GIT PULL] Btrfs fixes for 5.2-rc6

[David Sterba]

Hi,

please pull the following btrfs fixes:

- 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

Thanks.
