Subject: [Ocfs2-devel] dlm stress test hangs OCFS2

Thanks, Coly.

So dlmglue calls dlmlock to downconvert the lock from EX => NL.
However, in the next iteration, we see lock at PR. Strange.

Anycase, I have created a patch that should provide more info.
The patch is against the current mainline. It should apply against
older trees. But may require a bit of tlc.

Please re-run with the the following patch.
