[Cluster-devel] [PATCH v2 0/6] gfs2: Prepare for resource group glock sharing

[Andreas Gruenbacher <agruenba@redhat.com>]

This is an update of the resource group glock sharing patch queue by Bob
and myself.  Some of the cleanups and fixes posted previously [*] have
been integrated upstream in the meantime.

Patch "gfs2: Add local resource group locking" is now built on top of
the existing rgrp locking scheme; I'll get back to cleaning that up
later.

Steve was questioning the performance impact of patch "gfs2: Only use
struct gfs2_rbm for bitmap manipulations".  I still think it's a
non-issue, but some analysis will be useful.

This updated patch queue has passed initial testing.

Thanks,
Andreas
