From c41cfc6c5ba46050b416c0b0b2621cbe68c4669c Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 2 Feb 2017 12:45:58 +0100 Subject: sched/headers: Move the JOBCTL_ defines and methods from to Only a small fraction of sched.h users actually utilizes these defines, and they are not scheduler functionality in any case, so move them into their separate header. (Also make a self-contained header.)
