Subject: [PATCH 09/15] gfs2: Don't set GLF_LOCK in gfs2_dispose_glock_lru
Date: Tue, 9 Apr 2024 18:44:59 +0200 [thread overview]
Message-ID: <20240409164508.79570-10-agruenba@redhat.com> (raw)
In-Reply-To: <20240409164508.79570-1-agruenba@redhat.com>
In gfs2_dispose_glock_lru(), we want to skip glocks which are in the
process of transitioning state (as indicated by the set GLF_LOCK flag),
but we we don't need to set that flag for requesting a state transition.
