	check_isolcpus() clears ISOLCPUS before rebuilding it from sched domain data. Comparing that empty value with /sys/devices/system/cpu/isolated makes the test fail whenever isolcpus=domain is present. That sysfs file is generated from HK_TYPE_DOMAIN_BOOT and does not change when cpuset updates HK_TYPE_DOMAIN. Re-reading it cannot validate dynamic housekeeping updates. The cpuset.cpus.isolated and sched domain checks already cover the two dynamic interfaces, so remove the invalid comparison. This can be reproduced on a kernel booted with isolcpus=domain,15: # tools/testing/selftests/cgroup/test_cpuset_prs.sh The test fails its first state-matrix isolation check before the change and continues past that check afterward.

2026-08-24	docs: cgroup-v2: fix misc.events key format descriptiongrafted	Cheng Lingfei
	In misc cgroup, misc.events does not output a simple "max" key. Instead, each registered misc resource outputs a separate key suffixed with ".max" (i.e., "<res>.max"). Update the documentation to clarify that the entry key is "<res>.max".
