Miklos, could you explain why does lock_request() prohibit page faults until
the matching unlock_request()? All it does is setting FR_LOCKED on
our request and the only thing that even looks at that is fuse_abort_conn(),
which doesn't (AFAICS) wait for anything.
Where does the deadlock come from, and if it's not a deadlock - what is
it? Or is that comment stale since "fuse: simplify request abort"?
