No, I'm not saying that you shouldn't use configfs. Greg is
more adamant than I, actually, on the "file == attribute" model.
Here's the thing. For most users, there is no reason they can't
use configfs for _config_ and something like netlink for bulk data
movement. configfs isn't a kitchen sink, and it never should be.
Now, I know that your group/pids list fits really nicely as a
concept in the configfs tree. You certainly can't be calling a usermode
helper for each fork() and exit(). So this is why we're still having a
discussion and working on it.
