From af8601ad420f6afa6445c927ad9f36d9700d96d6 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 3 Feb 2017 09:57:00 +0100 Subject: kasan, sched/headers: Uninline kasan_enable/disable_current() is a low level header that is included early in affected kernel headers. But it includes which complicates the cleanup of sched.h dependencies. But kasan.h has almost no need for sched.h: its only use of scheduler functionality is in two inline functions which are not used very frequently - so uninline kasan_enable_current() and kasan_disable_current(). Also add a dependency to a .c file that depended on kasan.h including it. This paves the way to remove the include from kasan.h.
