From 314ff7851fc8ea66cbf48eaa93d8ebfb5ca084a9 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 3 Feb 2017 11:03:31 +0100 Subject: mm/vmacache, sched/headers: Introduce 'struct vmacache' and move it from to The header includes various vmacache related defines, which are arguably misplaced. Move them to mm_types.h and minimize the sched.h impact by putting all task vmacache state into a new 'struct vmacache' structure. No change in functionality.
