[PATCH] ocfs2: unlock rw lock if inode lock failed
In ocfs2_file_aio_write, it does ocfs2_rw_lock first and then
ocfs2_inode_lock. But if ocfs2_inode_lock failed, it goes to out_sems
without unlocking rw lock. This will cause a bug in ocfs2_lock_res_free
when testing res->l_ex_holders, which is increased in
__ocfs2_cluster_lock and decreased in __ocfs2_cluster_unlock.

dlm stress test hangs OCFS2
This email is also sent to cluster-devel at redhat.com. Since this issue is about
both dlm and ocfs2, I send the email here to look for help from upstream.
This is an already known issue.
on ocfs2 with user space cluster stack, run the test script from
http://people.redhat.com/~teigland/make_panic on the mounted ocfs2 volume from 2
nodes simultaneously, the access to ocfs2 volume on both nodes

[PATCH] ocfs2: Plugs race between the dc thread and an unlock ast message
This patch plugs a race between the downconvert thread and an unlock ast message.
Specifically, after the downconvert worker has done its task, the dc thread needs
to check whether an unlock ast made the downconvert moot.

[PATCH 0/62] Ocfs2 updates for 2.6.26-rc1
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
