From 63f609b160151c9e86b26b935c9671a23afe299f Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Mon, 6 Jan 2014 12:34:40 +0100 Subject: [PATCH] sched: Pass 'struct rq' to on_null_domain() The on_null_domain() function is getting the cpu to retrieve the struct rq associated with it. Pass 'struct rq' directly to the function as the caller already has the info.
