From 96e74ebf8d594496f3dda5f8e26af6b4e161e4e9 Mon Sep 17 00:00:00 2001 From: Valentin Schneider Date: Wed, 26 Feb 2020 12:45:43 +0000 Subject: sched/debug: Add task uclamp values to SCHED_DEBUG procfs Requested and effective uclamp values can be a bit tricky to decipher when playing with cgroup hierarchies. Add them to a task's procfs when SCHED_DEBUG is enabled.
