Subject: [PATCH] nspawn: move payload to sub-cgroup first, then sync cgroup
|
|
|
be3800 |
trees
|
|
|
be3800 |
|
|
|
be3800 |
if we sync the legacy and unified trees before moving to the right
|
|
|
be3800 |
subcgroup then ultimately the cgroup paths in the hierarchies will be
|
|
|
be3800 |
out-of-sync... Hence, let's move the payload first, and sync then.
