max-rss limits both pageable and locked physical memory used by projects, so
it is an overall physical memory cap. max-locked-memory is useful in limiting
applications which specifically lock physical memory. This is useful because
if the project locks up to it's max-rss, there will be no memory left for
it, and it will page non-stop. max-locked-memory can be set lower than
max-rss to protect against this.

There is no mechanism. swap limits are only on zones.
