Hmm. Is somebody (Michal?) looking at down_read_killable() too?

The VFS layer will want it with the pending parallel lookup code - the
inode semaphore is being converted to a rwsem, and there's a couple of
"killable" users.. The first step actually just wants to the exclusive
case (ie the write case that this adds), but I think the readdir code
could really use a reading version too..
