Merge tag 'for-5.2-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs fixes from David Sterba:
 "Notable highlights:

   - fixes for some long-standing bugs in fsync that were quite hard to
     catch but now finaly fixed

   - some fixups to error handling paths that did not properly clean up
     (locking, memory)

   - fix to space reservation for inheriting properties"
