Thanks for the report. For some reason I thought you had tried using softraid
crypto on a vnd and overlooked the fact that you were trying to use RAID 5
(and now RAID 1). To clarify, RAID 0, CONCAT and CRYPTO should all now work
on top of a vnd - RAID 1, RAID 4 and RAID 5 will still break in the manner
given below (panic related to active workunits). These disciplines require
the same changes that I've made to the other three, however they're a little
more complex and time consuming. I'll try to get to them fixed soon.
