hmmmm.
Linus's suggestion to add Scsi_Host to queuecommand seems to have had a
helpful side effect, exposing a minor bug present in nab's (v1), Andi's
(v2), my v3 and v4 push-down patches:
A few odd ducks, such as fas16 or ancient megaraid, call their own
->queuecommand directly. None of the major SCSI drivers do this,
thankfully.
The host lock push-down patch should be calling the _lck function in
those rare cases, otherwise we've created a deadlock.
Time for v5...
