Subject: sched/debug: Replace vruntime with wait_sum in /proc/sched_debug
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c5f3ab1c3b2e277cca6462415038dab02b4ad396;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sched/debug: Replace vruntime with wait_sum in /proc/sched_debug

Within runnable tasks in /proc/sched_debug, vruntime is printed twice,
once as tree-key and again as exec-runtime.

Since exec-runtime isnt populated in !CONFIG_SCHEDSTATS, use this field
to print wait_sum.
