Subject: [PATCH] cgroup: Respect DefaultMemoryMin when setting memory.min
c2dfb7
c2dfb7
This is an oversight from https://github.com/systemd/systemd/pull/12332.

Sadly the tests didn't catch it since it requires a real cgroup
c2dfb7
hierarchy to see, and it wasn't seen in prod since we're only currently
c2dfb7
using DefaultMemoryLow, not DefaultMemoryMin. :-(
