From cc5943a7816ba6c00639837a62131386619548dc Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 3 Jun 2013 19:13:55 -0700 Subject: [PATCH] cgroup: mark "notify_on_release" and "release_agent" cgroup files insane The empty cgroup notification mechanism currently implemented in cgroup is tragically outdated. Forking and execing userland process stopped being a viable notification mechanism more than a decade ago. We're gonna have a saner mechanism. Let's make it clear that this abomination is going away. Mark "notify_on_release" and "release_agent" with CFTYPE_INSANE.
