Hi nab:
Test
http://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git/scsi-mq,
it can't work for my machine(using ahci driver).
From this branch, i know it support ahci with scsi-mq/block-mq.So i modify some
place to make it can work.
For this patchset, i only test read/write and on oops/hung_task occur.
Jianpeng Ma (6):
block: support blk-mq on blk_run_queue/blk_run_queue_async.
scsi-mq: add operations about device_busy/target_busy/host_busy in
scsi_mq_queue_rq().
scsi-mq: Don't set QUEUE_FLAG_NONROT in scsi_mq_alloc_queue().
scsi-mq: init sg in scsi_init_io.
scsi-mq: fix 'BUG_ON(count > sdb->table.nents)' in
scsi_init_sgtable().
scsi-mq: Pre-allocation of sg tables base on
min(host->hostt->sg_tablesize, SCSI_MQ_MAX_SG_SEGMENTS).
