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.
