From: Tejun Heo Date: Tue, 4 Jun 2013 02:13:55 +0000 (-0700) Subject: cgroup: mark "notify_on_release" and "release_agent" cgroup files insane X-Git-Tag: upstream/snapshot3+hdmi~4814^2~14 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cc5943a7816ba6c00639837a62131386619548dc;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git 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cgroup files insane The empty cgroup notification mechanism currently implemented in cgroup is tragically outdated.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.
