-Subject: sched/fair: update_cfs_group() for throttled cfs_rqs
-
-From: Aaron Lu <ziqianlu@bytedance.com>
-
-[ Upstream commit fcd394866e3db344cbe0bb485d7e3f741ac07245 ]
-
-With task based throttle model, tasks in a throttled hierarchy are
-allowed to continue to run if they are running in kernel mode. For this
-reason, PELT clock is not stopped for these cfs_rqs in throttled
-hierarchy when they still have tasks running or queued.
-
-Since PELT clock is not stopped, whether to allow update_cfs_group()
-doing its job for cfs_rqs which are in throttled hierarchy but still
-have tasks running/queued is a question.
-
-The good side is, continue to run update_cfs_group() can get these
-cfs_rq entities with an up2date weight and that up2date weight can be
-useful to derive an accurate load for the CPU as well as ensure fairness
-if multiple tasks of different cgroups are running on the same CPU.
-OTOH, as Benjamin Segall pointed: when unthrottle comes around the most
-likely correct distribution is the distribution we had at the time of
-throttle.
-
-In reality, either way may not matter that much if tasks in throttled
-hierarchy don't run in kernel mode for too long. But in case that
-happens, let these cfs_rq entities have an up2date weight seems a good
-thing to do.
