This is a request for enabling the blk_mq disk scheduler by default. This
scheduler has been around for over an year, with the old one bound to be
deprecated in future kernel versions. The performance improvements of bfq over
cfq are noteworthy, this should bring a nice optimization to all users.

Currently the new scheduler requires the kernel parameter scsi_mod.use_blk_mq=1
to enable. The kernel needs to be compiled with the proper flags to use it
automatically. I believe other distros already consider blk_mq the standard
block queueing framework, openSUSE just needs to update its kernel build flags
if there are no objections to this change.
