Subject: [PATCH 3.12 015/124] ring-buffer-benchmark: Fix the wrong sched_priority of producer

From: Wang Long <long.wanglong@...wei.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 108029323910c5dd1ef8fa2d10da1ce5fbce6e12 upstream.

The producer should be used producer_fifo as its sched_priority,
so correct it.
