dlm updates for 3.7

Hi Linus,

Please pull dlm updates from tag:

git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm.git dlm-3.7

There are two main patches in this set, both related to the userland dlm_controld daemon. The first fixes a deadlock between dlm_controld and the dlm_send workqueue when both access configfs data simultaneously. The second reworks some code to get around a long standing, but intentional, unlock balance warning. The userland daemon no longer takes a lock that is later released from the kernel. The other commits are minor fixes and changes.

Thanks,
Dave
