Yes, I was surprised about that. We removed that tag from GFS2 back in
2010 it seems and I'm surprised that it didn't get removed from DLM at
around the same time. Either way though, it is a long time since either
have been experimental in reality, as both are stable and have many
users.

Also SCTP is only a (run time) option for DLM, and few users will
actually use it, since most people will use the TCP transport instead.

Anyway, this patch looks ok to me, so:
Acked-by: Steven Whitehouse <swhiteho@redhat.com>
