Why not? Perhaps I wasn't very specific when starting the thread.


It's certainly possible to do "not applicable" kinds of things with 
processes and their page cache, i.e.:

Or here, disabling O_DIRECT and sync would be sort of matching 
"feature-wise" with KVM's cache=writeback:

Is it possible to set things like this for all processes in a given lxc 
container?
