No, I think your patch do make sense. That is, it -does- make sense to be able to create a signal singalfd in a process and have N threads reading from it and getting either shared signals or their local private signals. I just don't like the actual implementation of it by changing the task pointer on the fly... My main issue is a matter of consistency of the signalfd API as a whole... the whole bloody thing is instanciated & attached to a thread in the first place. Maybe we should change that and say that one instanciates a signalfd on a thread group... that is, it always gets attached to the leader. It might well be that signalfd's concept of context is wrong in the first place and it should be attached to processes rather than threads and that made more explicit in the first place... but that leaves the door open to what a write() API should be ...
