Correct. > I cannot figure out what is this good for. Isn't tgid enough? You have to define "enough". The ignore feature can be implemented however we want. Like the old trusted feature, it is there for applications to allow themselves to be ignored (as well as have some control over _how_ they are ignored). It is possible that a multi-threaded application only wants one of its threads to be ignored because the other threads are doing tasks (such as downloading files) that should _not_ be ignored. > AFAIK old dazuko supports whole process(including its threads) to be > trusted and all you need to do is to call dazukoRegisterTrusted just > once for each process. Or am I missing something? Actually that is only partially correct. Dazuko 2.x also uses the task struct (individual threads) to implement the trusted feature. However, dazukoRegisterTrusted() also had a flag DAZUKO_TRUST_CHILDREN that would allow all the threads of the process and all children-processes to be trusted. The DazukoFS ignore feature does not have such an option because I could not find a safe method for traversing process trees. But we could expand the feature to allow configuring it to trust all threads of a process. This is technically not necessary. It would only be there as a convenience for developers.
