Merge tag 'gfs2-4.20.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2

Pull gfs2 updates from Bob Peterson:
 "We've got 18 patches for this merge window, none of which are very
  major:

   - clean up the gfs2 block allocator to prepare for future performance
     enhancements (Andreas Gruenbacher)

   - fix a use-after-free problem (Andy Price)

   - patches that fix gfs2's broken rgrplvb mount option (me)

   - cleanup patches and error message improvements (me)

   - enable getlabel support (Steve Whitehouse and Abhi Das)

   - flush the glock delete workqueue at exit (Tim Smith)"
