Hi Linus,

Please pull dlm updates from tag:

git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm.git dlm-7.4

This set contains several fixes for bugs found by static analysis,
fuzzing and code review. They mostly involve invalid input, e.g. from
userspace, configfs or remote nodes, and are unlikely to be seen in
normal usage.

Thanks,
Dave
