Roland, Linus, I'm sorry for being offtopic, but there is something I can't understand from the very beginning, when TIF_RESTORE_SIGMASK was introduced. On 03/28, Linus Torvalds wrote:Yes! Why do we need any flag? It looks a bit ugly. Isn't it better to introduce the new magic ERESTART_XXX which means ERESTARTNOHAND + restore-sigmask ? We only need this flag as an implicit parameter to the arch dependent do_signal() which we can't call directly, and thus it must imply TIF_SIGPENDING, and it is not valid after do_signal() (should be cleared). This all looks like ERESTART_ magic, why should we add something else ? See also http://marc.info/?l=linux-kernel&m=113734458516136 Of course, probably it is too late to change the implementation even if I am right, the question is: what I am missed? Oleg. --
