It would be more efficient to just attach directly to current->cgroups
rather than potentially creating/destroying one css_set for each
hierarchy until we've completely converged on current->cgroups - but
that would require a bunch of refactoring of the guts of
cgroup_attach_task() to ensure that the right can_attach()/attach()
callbacks are made. That doesn't really seem worthwhile right now for
the initial use, that I imagine isn't going to be
performance-sensitive.
Yes. In our use-case, this will be called only once per guest interface
when the guest comes up.
Hope you or someone more familiar with cgroups subsystem can optimize
this function later.
Thanks
