Description Michal Sekletar 2019-10-19 19:37:02 UTC

Description of problem:
RHEL-8 kernel has the support for memory.min memory cgroup protection. This protection is a natural follow-up (probably even more useful) on memory.low. Since the kernel supports it we should too.

Version-Release number of selected component (if applicable):
systemd-239-18.el8


How reproducible:
always

Steps to Reproduce:
1. man systemd.resource-control


Actual results:
MemoryMin= is not mentioned and is not supported.

Expected results:
MemoryMin= is fully supported and works as expected with cgroup v2.
