Just committed the new file system suspension API.  It replaces the
current vn_start_write/vn_finished_write API.  The suspension helpers
are now put into file system specific operations.  Therefore snapshots
of non-ffs file systems are currently unsupported.

Those using file system snapshots are encouraged to try this new API.
Take your favorite -current kernel and build with `options NEWVNGATE'.

Plan is to make the new API default in mid february 2007.

If the machine deadlocks and you have DDB compiled in, please
`call fstrans_dump' from DDB before reboot.

If you encounter problems, please send-pr with subject `fstrans ...'.
