bq. The constants should have ‘MEMORY’ in their names. For example,
CGROUP_PARAM_HARD_LIMIT is better named as CGROUP_PARAM_MEMORY_HARD_LIMIT in
order to avoid future collisions. This is similar to how BLKIO is used in the
previous line (classid should be fixed at some point too)
Fixed.
bq. Is the soft limit conf setting meant to represent a percentage or is it a
fraction between 0 and 1? From the default value of 0.9f and the application of
the soft limit it appears to be a fraction, but the name of the setting and its
validation check seem to indicate that it is meant to be a percentage. This
needs to be fixed.
Good catch. It's meant to be a percentage. Fixed.
