I think it shall be tested both on UP and SMP machines. So, yes,
UP testing (presumably, with PREEMPTION) is useful.

Please, wait a short time for new patch. Current patch has two issues:

1. recent BO_NEEDSGIANT changes prevent patch from applying. I need
to do a merge.
2. I have fixed deadlock that appears when shapshot is taken
on quota-enabled fs (this deadlock is specific to my patch).
Supposely, this is problem reported by Kris Kennaway.
