From 3116f0e3df0a67ad56f15dd4c5f6cefb04bb4a98 Mon Sep 17 00:00:00 2001 From: Paul Menage Date: Tue, 29 Apr 2008 01:00:04 -0700 Subject: CGroup API files: move "releasable" to cgroup_debug subsystem The "releasable" control file provided by the cgroup framework exports the state of a per-cgroup flag that's related to the notify-on-release feature. This isn't really generally useful, unless you're trying to debug this particular feature of cgroups. This patch moves the "releasable" file to the cgroup_debug subsystem.
