freebsd-skq/sys/fs
History
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.
