The spinlock of tgt_lock is only for serializing read and write
req_vq, one lockless seqcount is enough for the purpose.
On one 16core VM with vhost-scsi backend, the patch can improve

change_queue_depth allows changing per-target queue depth via sysfs.
It also allows the SCSI midlayer to ramp down the number of concurrent
inflight requests in response to a SCSI BUSY status response and allows
the midlayer to ramp the count back up to the device maximu
Christoph asked me to rebase the two virtio-scsi patches from

Note, I did a similar patch a while back, but then it was decided to
try and fix the tear-down ordering instead (which seems to have not
completely fixed the issue).
I've just tested this patch and i
