Subject: kcov: Remove kcov include from sched.h and move it to its users.
X-Git-Tag: v5.15~1260^2~60
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=183f47fcaa54a5ffe671d990186d330ac8c63b10;p=platform%2Fkernel%2Flinux-starfive.git

kcov: Remove kcov include from sched.h and move it to its users.

The recent addition of in_serving_softirq() to kconv.h results in
compile failure on PREEMPT_RT because it requires
task_struct::softirq_disable_cnt. This is not available if kconv.h is
included from sched.h.

It is not needed to include kconv.h from sched.h. All but the net/ user
already include the kconv header file.

Move the include of the kconv.h header from sched.h it its users.
Additionally include sched.h from kconv.h to ensure that everything
task_struct related is available.
