6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andreas Gruenbacher <agruenba@xxxxxxxxxx>
[ Upstream commit 59f60005797b4018d7b46620037e0c53d690795e ]
This consistency check was originally added by commit 9287c6452d2b1
("gfs2: Fix occasional glock use-after-free"). It is ill-placed in
gfs2_glock_free() because if it holds there, it must equally hold in
__gfs2_glock_put() already. Either way, the check doesn't seem
necessary anymore.
