This sounds interesting. Will this also be namespace-based like the sysctls
in the current patch? Will this future change integrate nicely with the current
new sysctls? This might allow to activate smc for containers, selectively. 

Please send these changes in a patch series together when they are finished.
We would like to review them as a whole to see how things play together.

Thank you!
