[PATCH 2/2] virtio: virtio_scsi: Set can_queue to the length of the virtqueue.
Since switching to blk-mq as the default in commit 5c279bd9e406
("scsi: default to scsi-mq"), virtio-scsi LUNs consume about 10x as
much kernel memory.
qemu currently allocates a fixed 128 entry virtqueue. can_queue
currently is set to 1024. But with indirect descriptors, each command
in the queue takes 1 virtqueue entry, so the number of commands which
can be queued is equal to the

[PATCH V6 0/5] virtio-scsi multiqueue
This series implements virtio-scsi queue steering, which gives
performance improvements of up to 50% (measured both with QEMU and
tcm_vhost backends).
This version rebased on Rusty's virtio ring rework patches, which
has already gone into virtio-next today.
We hope this can go into virtio-next together with the virtio ring
rework pathes.

[PATCH 0/2] virtio-scsi fixes for 3.6
James,
patch 1 fixes scanning of LUNs whose number is greater than 255. QEMU
passes a max_lun of 16383 (because it uses SAM numbering) but in Linux
it must become 32768 (because LUNs above 255 are "relocated" to 16640).
Patch 2 is a resubmission of the patch for online resizing of virtio-scsi
LUNs, which needs to be rebased.
LUNs above 255 now work for all of scanning, hotplug,

[PATCH v3 0/5] virtio-scsi multiqueue
This series implements virtio-scsi queue steering, which gives
performance improvements of up to 50% (measured both with QEMU and
tcm_vhost backends). The patches build on top of the new virtio APIs
at http://permalink.gmane.org/gmane.linux.kernel.virtualization/18431;
the new API simplifies the locking of the virtio-scsi driver nicely,
thus it makes sense to require them as a prerequisite.

Looks like there's active discussion on virtio tc mailing list.
