- Last cycle deferred css teardown on cgroup removal until the cgroup depopulated, so a css is not taken offline while tasks can still reference it. Disabling a controller through cgroup.subtree_control still had the same problem. This reworks the deferral from per-cgroup to per-css so that path is covered too. - New RDMA controller monitoring files: rdma.peak for per-device peak usage and rdma.events / rdma.events.local for resource-limit exhaustion. The max-limit parser was rewritten, fixing two input parsing bugs. - cpuset: fix a sched-domain leak on the domain-rebuild failure path and skip a redundant hardwall ancestor scan on v2. - Misc: pair the remaining lockless cgroup.max.* reads with WRITE_ONCE, assorted selftest robustness fixes, and doc path corrections. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCajB0sw4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGTZQAPwJy730XnUGvLqSiNZT05xzoq6G16u0cC61/U0g t+yU3wEA4mvObdARiJufo+f3Nsg1NY0NzF82xrCS60EsY+rXCgQ= =H56K -----END PGP SIGNATURE----- Merge tag 'cgroup-for-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull cgroup updates from Tejun Heo: - Last cycle deferred css teardown on cgroup removal until the cgroup depopulated, so a css is not taken offline while tasks can still reference it.
