[PATCH 1/2] virtio-scsi: replace target spinlock with seqcount

2014-07-06 Thread Paolo Bonzini
From: Ming Lei 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 IOPS with 3% on random read test. Signed-off-by: Ming Lei [Add initialization in virtscsi_targ

[PATCH 2/2] virtio-scsi: Implement change_queue_depth for virtscsi targets

2014-07-06 Thread Paolo Bonzini
From: Venkatesh Srinivas 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

[PATCH 0/2] virtio-scsi queue for 3.17

2014-07-06 Thread Paolo Bonzini
