Subject: [PATCH] cgroup: Mark memory protections as explicitly set in
c2dfb7
 transient units
c2dfb7
c2dfb7
A later version of the DefaultMemory{Low,Min} patch changed these to
c2dfb7
require explicitly setting memory_foo_set, but we only set that in
c2dfb7
load-fragment, not dbus-cgroup.
c2dfb7
c2dfb7
Without these, we may fall back to either DefaultMemoryFoo or
c2dfb7
CGROUP_LIMIT_MIN when we really shouldn't.
c2dfb7
c2dfb7
(cherry picked from commit 184e989d7da4648bd36511ffa28a9f2b469589d1)
