[GIT PULL] gfs2 fixes for 5.16

[Andreas Gruenbacher]

Hi Linus,

please consider pulling the following gfs2 fixes for 5.16.  These are on
top of the memory map + page fault fixes from my first pull request
earlier today.

Thanks,
Andreas

  gfs2: Fix unused value warning in do_gfs2_set_flags() (2021-10-25 08:42:20 +0200)

----------------------------------------------------------------
Changes in gfs2:

* Fix a locking order inversion between the inode and iopen glocks in
  gfs2_inode_lookup.

* Implement proper queuing of glock holders for glocks that require
  instantiation (like reading an inode or bitmap blocks from disk).
  Before, multiple glock holders could race with each other and
  half-initialized objects could be exposed; the GL_SKIP flag further
  exacerbated this problem.

* Fix a rare deadlock between inode lookup / creation and remote delete
  work.

* Fix a rare scheduling-while-atomic bug in dlm during glock hash table
  walks.

* Various other minor fixes and cleanups.
