Christian LoehleandGreg Kroah-Hartman 6c8b1efdc4 sched/debug: Provide slice length for fair tasks ...

[ Upstream commit 9065ce6975 ]

Since commit:

  857b158dc5 ("sched/eevdf: Use sched_attr::sched_runtime to set request/slice suggestion")

... we have the userspace per-task tunable slice length, which is
a key parameter that is otherwise difficult to obtain, so provide
it in /proc/$PID/sched.

[ mingo: Clarified the changelog. ]
