# HEAD: 4fd5750af02ab7bba7c58a073060cc1da8a69173 sched,tracing: Convert to
sched_set_fifo()
This tree adds the sched_set_fifo*() encapsulation APIs to remove
static priority level knowledge from non-scheduler code.
The three APIs for non-scheduler code to set SCHED_FIFO are:
- sched_set_fifo()
- sched_set_fifo_low()
- sched_set_normal()
These are two FIFO priority levels: default (high), and a 'low' priority level,
plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
Since the changes affect a lot of non-scheduler code, we kept this in a separate
tree.
When merging to the latest upstream tree there's a conflict in
drivers/spi/spi.c,
which can be resolved via:
sched_set_fifo(ctlr->kworker_task);

Thanks,
Ingo
