Currently, o2net_accept_one() is allowed to accept a connection from listening node itself, such a fake connection will not be successfully established due to no handshake detected afterwards, and later end up with triggering connecting worker in a loop. We're going to fix this by treating such connection request as 'invalid', since we've got no chance of requesting connection

This fix modifies o2net layer behavior which seems to trigger some DLM race issues during umount/evictions that needs to be fixed as well. I am working on the dlm issues but meanwhile please review this patch. Thanks, --Srini

This is a forward port for net_proc.c from 1.2.

All, This is hopefully the final drop of the patches for adding global heartbeat to the o2cb stack. The diff from the previous set is here: http://oss.oracle.com/~smushran/global-hb-diff-2010-10-07 Implemented most of the suggestions provided by Joel and Wengang. The most important one was to activate the feature only at the end, Also, got mostly a clean run with checkpatch.pl. Sunil

I'm running a bit late with the e-mail this time around, but I think that's ok since there really isn't any major new features here - the bulk of the Ocfs2 update is bug fixes, or cleanups. The same goes for configfs. The only two things that could be described as features would be: - Sunil has updated Ocfs2 to provide even more live cluster locking information via debugfs. - Joel

The following series of patches comprises the bulk of our outstanding changes for Ocfs2. Aside from the usual set of cleanups and fixes that were inappropriate for 2.6.25, there are a few highlights: The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location meshes better with modern sysfs layout. A symbolic link has been placed in the old location so as to
