From ef8bd77f332bb0a4e467d7171bbfc6c57aa08a88 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 8 Feb 2017 18:51:36 +0100 Subject: sched/headers: Prepare for new header dependencies before moving code to We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.
