One potential problem I can think of with writing a slab controller
would be that the user would have to estimate what fraction of the
amount of memory slab should be allowed to use, which might not be
ideal.
If you wanted to limit a cgroup to a total of 1GB of memory, you might
not care if the job wants to use 0.9 GB of user memory and 0.1GB of
slab or if it wants to use 0.9GB of slab and 0.1GB of user memory..
Because of this, it might be more practical to integrate the slab
accounting in memcg.
