Under this circumstance, both seem > equivalent from my PoV. I'm confused. One of us misunderstands the whole thing. Examples of both controllers: task_counter: task.limit=2. Let's say the only process in that group forks, then you have two processes. Forking is disallowed from now on. The child process exits, and there's only one left - which is allowed to fork! The group may bounce between 0 and 2 processes forever. cgroup_fork: fork.remaining=2. Now let's say we have one thousand processes in that group! One of those forks (allowed). And it forks again (allowed). And tries again - blocked because "fork.remaining" has reached zero. We have 1002 processes; when 1001 of those processes exit, one remains, but it is still disallowed to fork, because "fork.remaining" is still zero. It will remaing zero until somebody with write permissions raises it again. Did I get it wrong? To me, that is not look equivalent at all.
