The vast majority of the rwlocks in lockstat output are vnode
locks, for which it only displays genfs_lock as the taker of
the lock. It might be nice if it were easier to see who wanted
the lock in order to get an idea of which operations the
contention lies in.
Run lockstat while doing file system stuff. Fail to attain
enlightenment. Put on a sad face.
