yay, we actually used all this code for something ;)
I don't think we really saw a comprehensive list of what else the kmem
controller will be used for, but I believe that all other envisaged
applications will require slab accounting, yes?
So it appears that all we have at present is a
yet-another-fork-bomb-preventer, but one which requires that the
culprit be in a container? That's reasonable, given your
hosted-environment scenario. It's unclear (to me) that we should merge
all this code for only this feature. Again, it would be good to have a
clear listing of and plan for other applications of this code.
