Subject: [PATCH] cgroup: Add cgroup_enable option
|
|
|
|
The upstream addition of the kernel parameter cgroup_disable makes it
|
|
possible to configure cgroups at boot time. In theory, re-enabling a
|
|
disabled cgroup is simply a case of removing the relevant cgroup_disable
|
|
setting, but this is difficult if the setting comes from Device Tree.
|
|
|
|
Re-introduce cgroup_enable as a way around the problem.
