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). block/blk-core.c | 21 ++++++++++++++------- drivers/scsi/scsi-mq.c | 33 ++++++++++++++++++++++++++++----- drivers/scsi/scsi_lib.c | 4 +++- 3 files changed, 45 insertions(+), 13 deletions(-) -- 1.7.10.4 ÿôèº{.nÇ+?·?®??+%?Ëÿ±éݶ¥?wÿº{.nÇ+?·¥?{±þÇ,?ø§¶?¡Ü¨}©?²Æ zÚ&j:+v?¨þø¯ù®w¥þ?à2?Þ?¨èÚ&¢)ß¡«a¶Úÿÿûàz¿äz¹Þ?ú+?ù???Ý¢jÿ?wèþf
