commit f3b6ea990e81e9234903a7fb65565f7dd3d3d43f
Author: Lon Hohberger <lhh@redhat.com>
Date: Fri Apr 18 14:19:07 2008 -0400

[fence] Close file descriptors that are in invalid/error states

If poll was returning with a file descriptor noted as active,
but with the POLLERR/POLLNVAL flags set (but not POLLIN or
POLLHUP), fenced and groupd would enter a tight spin loop.

This fixes that condition.

commit 0fdda26db52d31e20d0524168859dfbffce4ffa0
Author: Benjamin Marzinski <bmarzins@redhat.com>
Date: Thu Apr 17 11:41:09 2008 -0500

The gnbd kernel module on 64 bit architectures didn't handle ioctls from 32 bit
userspace processes. Now it does.
Resolves: bz #440454

Also, I was getting an error because on ppc64, the manual definition of O_DIRECT
in gnbd/server/device.c was incorrect. I switched to defining _GNU_SOURCE, which
should mean that O_DIRECT will be automatically defined.

commit 89c885f73b4d90c2be407125d62379fb32a11e3e
Author: Lon Hohberger <lhh@redhat.com>
Date: Wed Nov 14 17:17:15 2007 +0000

Remove clushutdown man page references from clusvcadm.8; resolves #324151

commit a286ab41b67c9b6cd22fb88d862375e09259639e
Author: Fabio M. Di Nitto <fdinitto@redhat.com>
Date: Tue Apr 22 09:36:30 2008 +0200
