Konstantin Belousov	25809a018d	mntfs: lock mntfs pseudo devfs vnode properly ... Require devvp locked for mntfs_freevp(), to have it locked around vgone(). Make that true for ffs, which is the only consumer of the interface.

Chuck Silvers	f15ccf8836	Add a new "mntfs" pseudo file system which provides private device vnodes for ... file systems to safely access their disk devices, and adapt FFS to use it. Also add a new BO_NOBUFS flag to allow enforcing that file systems using mntfs vnodes do not accidentally use the original devfs vnode to create buffers.
