Merge tag 'dlm-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm
Pull dlm updates from David Teigland: - Allow blocking posix lock requests to be interrupted while waiting. This requires a cancel request to be sent to the userspace daemon where posix lock requests are processed across the cluster. - Fix a posix lock patch from the previous cycle in which lock requests from different file systems could be mixed up. - Fix some long standing problems with nfs posix lock cancelation. - Add a new debugfs file for printing queued callbacks. - Stop modifying buffers that have been used to receive a message. - Misc cleanups and some refactoring. * tag 'dlm-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm: dlm: fix plock lookup when using multiple lockspaces fs: dlm: don't use RCOM_NAMES for version detection fs: dlm: create midcomms nodes when configure fs: dlm: constify receive buffer fs: dlm: drop rxbuf manipulation in dlm_recover_master_copy fs: dlm: drop rxbuf manipulation in dlm_copy_master_names fs: dlm: get recovery sequence number as parameter fs: dlm: cleanup lock order fs: dlm: remove clear_members_cb fs: dlm: add plock dev tracepoints fs: dlm: check on plock ops when exit dlm fs: dlm: debugfs for queued callbacks fs: dlm: remove unused processed_nodes fs: dlm: add missing spin_unlock fs: dlm: fix F_CANCELLK to cancel pending request fs: dlm: allow to F_SETLKW getting interrupted fs: dlm: remove twice newline
