From 166ad0e1e2132ff0cda08b94af8301655fcabbcd Mon Sep 17 00:00:00 2001 From: Kefeng Wang <wangkefeng.wang@huawei.com> Date: Wed, 7 Dec 2016 14:44:36 -0800 Subject: [PATCH] kcov: add missing #include <linux/sched.h> In __sanitizer_cov_trace_pc we use task_struct and fields within it, but as we haven't included <linux/sched.h>, it is not guaranteed to be defined. While we usually happen to acquire the definition through a transitive include, this is fragile (and hasn't been true in the past, causing issues with backports). Include <linux/sched.h> to avoid any fragility.
