Hmm, I'm not aware of any mm->mmap_sem starvation issues in 3.18-rc, maybe
this is a duplicate of another issue that someone has reported that I
haven't seen. The lengthy output of echo t > /proc/sysrq-trigger should
give a clue as to what is holding it or perhaps this is a more generic
rwsem issue.
