From: Ingo Molnar Date: Fri, 3 Feb 2017 08:57:00 +0000 (+0100) Subject: kasan, sched/headers: Uninline kasan_enable/disable_current() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=af8601ad420f6afa6445c927ad9f36d9700d96d6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
