Subject: [GIT PULL] dlm updates for 6.2
Date: Mon, 12 Dec 2022 11:43:32 -0600 [thread overview]
Message-ID: <20221212174332.GA9261@redhat.com> (raw)
Hi Linus,
Please pull dlm updates from tag:
git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm.git dlm-6.2
These patches include the usual cleanups and minor fixes, removal of code
that is no longer needed due to recent improvements, and improvements to
processing large volumes of messages during heavy locking activity.
- Misc code cleanup.
- Fix a couple socket handling bugs: a double release on an error path
and a data-ready race in an accept loop.
- Remove code for resending dir-remove messages. This code is no longer
needed since the midcomms layer now ensures the messages are resent if
needed.
- Add tracepoints for dlm messages.
- Improve callback queueing by replacing the fixed array with a list.
- Simplify the handling of a remove message followed by a lookup
message by sending both without releasing a spinlock in between.
- Improve the concurrency of sending and receiving messages by holding
locks for a shorter time, and changing how workqueues are used.
- Remove old code for shutting down sockets, which is no longer needed
with the reliable connection handling that was recently added.
Thanks,
Dave
