This is a further reminder.

So far I've not seen any improvement over the locking of any of our
'legacy' filesystems. I remind you that this may be meaning
disconnecting them from the tree on 1st Semptember 2012, accordingly
with this road-map:
http://wiki.freebsd.org/NONMPSAFE_DEORBIT_VFS

In one month I'm going to disable VFS_ALLOW_NONMPSAFE by defaults in
order to see how well the users do with this option down. At the
present times this means that from 1st March you won't be able to
mount smbfs or ntfs volumes, for example.

Please step up and fix your favourite filesystem.

Thanks,
Attilio
