Roland McGrath b74d0deb96 Restrict clearing TIF_SIGPENDING ... This patch should get a few birds. It prevents sigaction calls from clearing TIF_SIGPENDING in other threads, which could leak -ERESTART*. And It fixes ptrace_stop not to clear it, which done at the syscall exit stop could leak -ERESTART*. It probably removes the harm from signalfd, at least assuming it never calls dequeue_signal on kernel threads that might have used block_all_signals.
