Subject: [PATCH] core: tiny tweak for cgroup trimming during manager_free()
|
|
|
661545 |
|
|
|
661545 |
Instead of blacklisting when not to trim the cgroup tree, let's instead
|
|
|
661545 |
whitelist when to do it, as an excercise of being careful when being
|
|
|
661545 |
destructive.
|
|
|
661545 |
|
|
|
661545 |
This should not change behaviour with exception that during switch roots
|
|
|
661545 |
we now won't attempt to trim the cgroup tree anymore. Which is more
|
|
|
661545 |
correct behaviour after all we serialize/deserialize during the
|
|
|
661545 |
transition and should be needlessly destructive.
|
|
|
661545 |
|
|
|
661545 |
(cherry picked from commit 86036b26a1da4d90ca274d37e77c56980ab689fd)
