Subject: [Cluster-devel] [PATCH 04/19] GFS2: Do not reset flags on active reservations
Date: Mon,  4 Nov 2013 11:09:27 +0000	[thread overview]
Message-ID: <1383563382-8535-5-git-send-email-swhiteho@redhat.com> (raw)
In-Reply-To: <1383563382-8535-1-git-send-email-swhiteho@redhat.com>

From: Bob Peterson <rpeterso@redhat.com>

When we used try locks for rgrps on block allocations, it was important
to clear the flags field so that we used a blocking hold on the glock.
Now that we're not doing try locks, clearing flags is unnecessary, and
a waste of time. In fact, it's probably doing the wrong thing because
it clears the GL_SKIP bit that was set for the lvb tracking purposes.
