v3.13-rc2?
1) That's a bit old as there's actually several 3.13 stable releases now.
2) It doesn't appear correct anyway, since the trace reports 3.14-rc5+
(Meanwhile, I'm not a dev so no comment on the root question.)

Whoops, that's my mistake.. it's 3.14-rc5. The exact commit is it
git://github.com/ceph/ceph-client.git, if it matters; it's -rc5 + some
ceph patches.
Thanks!
