From: Wang Long <[email protected]>
The {producer|consumer}_{nice|fifo} parameters are integer
type, we should use 'int' as the second param in module_param.
For example(consumer_fifo):
the default value of consumer_fifo is -1.
Without this patch:
# cat /sys/module/ring_buffer_benchmark/parameters/consumer_fifo
4294967295
With this patch:
# cat /sys/module/ring_buffer_benchmark/parameters/consumer_fifo
-1
