+         delayed due to contention of the respective resource.

+         In kernels with cgroup support, cgroups (cgroup2 only) will

+         This feature adds some code to the task wakeup and sleep

+         common scheduling-intense workloads in practice (such as
+         webservers, memcache), but it does show up in artificial
+         scheduler stress tests, such as hackbench.
