[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.
V6: rework "redo allocation of target data"

[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 0/2] 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 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.
