From 6b6350f155afdfdf888e18c7bf26950a6d10b0c2 Mon Sep 17 00:00:00 2001 From: Dongsheng Yang Date: Mon, 27 Jan 2014 17:15:38 -0500 Subject: sched: Expose some macros related to priority Some macros in kernel/sched/sched.h about priority are private to kernel/sched. But they are useful to other parts of the core kernel. This patch moves these macros from kernel/sched/sched.h to include/linux/sched/prio.h so that they are available to other subsystems.
