Memory controller had begun to print warning messages when using some
attributes that do no have a counterpart in its cgroup v2
implementation. This is informative to users who run (unwittingly) on v1
or to distros that run v1 (they can learn about such users or prepare
for disabling v1 configs).
I consider the deprecated files in three categories:
- RE) replacement exists,
- DN) dropped as non-ideal concept (e.g. non-hierarchical resources),
- NE) not evaluated (yet).
For RE, I added the replacement into the warning message, DN have only a
plain deprecation message and I marked the commits with NE as RFC.
Also I'd be happy if you would point out some forgotten knobs that'd
deserve similar warnings.
At the end are some cleanup patches I encountered en route.
