Merge tag 'gfs2-v5.16-rc4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2
Pull gfs2 fixes from Andreas Gruenbacher:
- Since commit 486408d690e1 ("gfs2: Cancel remote delete work
asynchronously"), inode create and lookup-by-number can overlap more
easily and we can end up with temporary duplicate inodes. Fix the
code to prevent that.
- Fix a BUG demoting weak glock holders from a remote node.
* tag 'gfs2-v5.16-rc4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2:
gfs2: gfs2_create_inode rework
gfs2: gfs2_inode_lookup rework
gfs2: gfs2_inode_lookup cleanup
gfs2: Fix remote demote of weak glock holders
