SVN rev 184591 on 2008-11-03 14:11:06Z by kib
In vfs_busy(), lockmgr() cannot legitimately sleep, because code checked
MNTK_UNMOUNT before, and mnt_mtx is used as interlock. vfs_busy() always
tries to obtain a shared lock on mnt_lock, the other user is unmount who
tries to drain it, setting MNTK_UNMOUNT before.
