Your fix seems like the only way to go. From skimming all the ERESTART* uses, I think that in all cases (except for n_tty.c:job_control before your patch), TIF_SIGPENDING is indeed set when a thread returns -ERESTART*.
But it makes me realize that there is a danger of leaking a -ERESTART* return code to userland when TIF_SIGPENDING gets cleared by another thread doing a recalc_sigpending_tsk. Because of -ERESTART* I think we must make it a rule that no thread can clear another thread's TIF_SIGPENDING, only set it (unless it's known to be stopped in the signal code or something). >From our recent work on it, I think that do_sigaction is in fact the only place this can happen. So that says we should err in the other direction from what I said before in do_sigaction, and not have it do recalc at all.
