Subject: [PATCH] cgroup: always enable memory.use_hierarchy= for all cgroups
|
|
|
a4b143 |
in the memory hierarchy
|
|
|
a4b143 |
|
|
|
a4b143 |
The non-hierarchial mode contradicts the whole idea of a cgroup tree so
|
|
|
a4b143 |
let's not support this. In the future the kernel will only support the
|
|
|
a4b143 |
hierarchial logic anyway.
