ring-buffer-benchmark: Fix the wrong param in module_param
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 Link: http://lkml.kernel.org/r/1433923873-67712-1-git-send-email-long.wanglong@huawei.com Signed-off-by: Wang Long <long.wanglong@huawei.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
