From b2d5bfea2d00a0000da18f7667c2b0e2c2f168d9 Mon Sep 17 00:00:00 2001 From: Ingo Molnar <mingo@kernel.org> Date: Mon, 6 Feb 2017 09:56:40 +0100 Subject: [PATCH] sched/headers, timers: Remove the <linux/sysctl.h> include from <linux/timer.h> So we want to simplify <linux/sched.h>'s header dependencies, but one roadblock of that is <linux/timer.h>'s inclusion of sysctl.h, which brings in other, problematic headers. Note that timer.h's inclusion of sysctl.h can be avoided if we pre-declare ctl_table - so do that.
