Subject[PATCH 0/2] AIO add per-command iopriority
Date
From: Adam Manzanares <adam.manzanares@wdc.com>

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.

See the following link for performance implications on a SATA HDD:
