Subject: [GIT PULL] dlm updates for 6.11

Hi Linus,

Please pull dlm updates from tag:

git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm.git dlm-6.11

Note, this set includes a patch touching drivers/md/md-cluster.c, acked
by the md-cluster developers, making use of the new DLM_LSFL_SOFTIRQ_SAFE
flag.  Overall, changes include:

- New flag DLM_LSFL_SOFTIRQ_SAFE can be set by code using dlm
  to indicate callbacks can be run from softirq.
- Change md-cluster to set DLM_LSFL_SOFTIRQ_SAFE.
- Clean up for previous changes, e.g. unused code and parameters.
- Remove custom pre-allocation of rsb structs which is unnecessary
  with kmem caches.
- Change idr to xarray for lkb structs in use.
- Change idr to xarray for rsb structs being recovered.
- Change outdated naming related to internal rsb states.
- Fix some incorrect add/remove of rsb on scan list.
- Use rcu to free rsb structs.

Thanks,
Dave
