scsi: default to scsi-mq
Remove the SCSI_MQ_DEFAULT config option and default to the blk-mq I/O path now that we had plenty of testing, and have I/O schedulers for blk-mq. The module option to disable the blk-mq path is kept around for now. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

This option enables the new blk-mq based I/O path for SCSI

devices by default. With the option the scsi_mod.use_blk_mq
|

module/boot option defaults to Y, without it to N, but it can

still be overridden either way.

If unsure say N.
