Merge tag 'dlm-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm
Pull dlm updates from David Teigland:
"This is a major dlm networking enhancement that adds message
retransmission so that the dlm can reliably continue operating when
network connections fail and nodes reconnect.
Previously, this would result in lost messages which could only be
handled as a node failure"
