ring-buffer-benchmark: Add parameters to set produce/consumer priorities
Running the ring-buffer-benchmark's threads at the lowest priority may work well for keeping it in the background, but it is not appropriate for the benchmarks. This patch adds 4 parameters to the module: consumer_fifo consumer_nice producer_fifo producer_nice By default the consumer and producer still run at nice +19. If the *_fifo options are set, they will override the *_nice values. modprobe ring_buffer_benchmark consumer_nice=0 producer_fifo=10 The above will set the consumer thread to a nice value of 0, and the producer thread to a RT SCHED_FIFO priority of 10. Note, this patch also fixes a bug where calling set_user_nice on the consumer thread would oops the kernel when the parameter "disable_reader" is set.
