Subject: [GIT PULL] cgroup changes for v5.14-rc1
Date: Thu, 1 Jul 2021 10:55:40 -1000 [thread overview]
Message-ID: <YN4rzCdUR+/2LgaP@mtj.duckdns.org> (raw)
Hello, Linus.
* cgroup.kill is added which implements atomic killing of the whole subtree.
Down the line, this should be able to replace the multiple userland
implementations of "keep killing till empty".
* PSI can now be turned off at boot time to avoid overhead for
configurations which don't care about PSI.
Thank you.
