This is the per-I/O equivalent of the ioprio_set system call.
When IOCB_FLAG_IOPRIO is set on the iocb aio_flags field, then we set the
newly added kiocb ki_ioprio field to the value in the iocb aio_reqprio field.

This patchset interprets the aio_reqprio field of an iocb as a
per-command value iff the RWF_IOPRIO flag is set on the iocb.
This feature is implemented for a block device, but could also be
leveraged by any consumers of the iocb

This is the per-I/O equivalent of the ioprio_set system call.
When the RWF_IOPRIO flag is set then the aio_reqprio field of the iocb
is interpreted as an I/O scheduling class and priority.

This patch adds support for request iopriority handling in the
mpt3sas layer. This works only when a ATA device is behind the
SATL. The ATA device also has to indicate that it supports
command priorities in the identify information that is pulled from
the SATL.
