No, after further discussion we came to the conclusion that introducing the bit actually saves us only a couple of user-to-kernel/kernel-to-user copies in do_exit(), but it complicates the kernel exit path, so it's not really worth it. Shaohua didn't call it arch_ptrace_resume(), but he added an argument to arch_ptrace_stop(). I was already testing a different variant of that patch and I'm sorry if it caused confusion. :( Is there any other advantage in introducing TIF_RESTORE_RSE than saving some unneeded data copying?
