Subject: [GIT PULL] dlm updates for 6.12

Hi Linus,

Please pull dlm updates from tag:

git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm.git dlm-6.12

Summary:

- Remove some unnecesary hold/unhold rsb refcounting
  in cases where an existing refcount is known to exist.
- Remove some unnecessary checking for zero nodeids, which
  should never exist, and add some warning if they do.
- Make the slow freeing of structs in release_lockspace()
  async, run from a workqueue.
- Prior rcu freeing allows some further struct lookups to
  run without a lock.
- Use blocking kernel_connect on sockets to avoid EINPROGRESS.

Thanks,
Dave
