[PATCH v2 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 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.

[PATCH 0/5] Multiqueue virtio-scsi
Hi all,
this series adds multiqueue support to the virtio-scsi driver, based
on Jason Wang's work on virtio-net. It uses a simple queue steering
algorithm that expects one queue per CPU. LUNs in the same target always
use the same queue (so that commands are not reordered); queue switching
occurs when the request being queued is the only one for the target.

SCSI driver for VMware's virtual HBA - V6.
Here is the V6, which addresses most of the suggestions from Chris'.
Please consider this for the scsi-tree.
Thanks,

VMware PVSCSI driver - v6.
Changelog (v6-v5)
- remove unneeded header file includes.
- make pvscsi_dev as a static function.
- IRQF_SHARED only for INT/X, pass zero for rest.
- use __get_free_pages to allocate ctx->sgl.
