As explained in my earlier proposal I think we need to move to blk-mq for the SCSI midlayer quickly, and in a way that keeps all the existing queueing mechanisms working. This series shows my current progress towards this goal. It works under medium loads for iSCSI and virtio_scsi and I'm fairly happy with the code structure. As seen I've tried to push as much work into the blk-mq core, and refactor the SCSI code so that it can be used for the old request based path and blk-mq as much as possible.
There are still lots of limits mostly due to the lack of functionality in blk-mq, and I will try to address these in the blk-mq core mostly. A git tree is also available at git://git.infradead.org/users/hch/scsi.git#scsi-mq-wip This work was sponsored by the ION division of Fusion IO. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
