I don't see any ioprio code being integrated into workqueue in your
patchset, from which what you need might be:
struct ioprio_work {
/******* the work item to be scheduled *******/
struct work_struct work;
/******* the stuff need for ioprio ******/
/* If the work does submit_bio, io priority may be needed. */
unsigned short ioprio;
/* Record kworker's original io priority. */
unsigned short ori_ioprio;
/* Whether the work has set io priority? */
long ioprio_flag;
}
And if ioprio needs to be integrated into workqueue, it should be attributes
added to the workqueue itself as in the struct workqueue_attrs.
Thanks
