Hmm. Seems a bit fancier than necessary, but maybe reasonable. I'll probably start with a single file listing all the different container associations and we can turn it into a directory later as a finishing touch. > > Or how about each controller type, such as cpusets, having its own > /proc/<pid>/<controller-type> file, with no generic file > /proc</pid>/container at all.

If not, then every container subsystem would involve a patch in fs/proc/base.c, which seems a bit nasty. > However this fits in nicely with my expectation that we will have > only limited need, if any, in the short term, to run systems with > both cpusets and resource groups at the same time. We're currently planning on using cpusets for the memory node isolation properties, but we have a whole bunch of other resource controllers that we'd like to be able to hang off the same infrastructure, so I don't think the need is that limited. > > And while we're here, how about each controller naming itself with a > well known string compiled into its kernel code, and a file such > as /proc/containers listing what controllers are known to it? Not The naming is already in my patch. You can tell from the top-level directory which containers are registered, since each one has an xxx_enabled file to control whether it's in use; there's not a separate /proc/containers file yet.
