[Cluster-devel] [PATCH 04/19] GFS2: Do not reset flags on active reservations



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.
