Merge tag 'dlm-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm
Pull dlm updates from David Teigland:
"This set mainly includes a change to the way the dlm uses the SCTP API
in the kernel, removing the direct dependency on the sctp module.
Other odd SCTP-related fixes are also included.
The other notable fix is for a long standing regression in the
behavior of lock value blocks for user space locks"
