So this replaces signal-kill-the-obsolete-signal_unkillable-check-in-complete_signal.patch 2/3 is actually the same change, just the changelog was updated.
I'll try to send the cleanups tomorrow. sig_task_ignored() doesn't look nice, sig_handler_ignored() must die, SIGNAL_UNKILLABLE checks in sig_task_ignored() and get_signal() should be unified.
And to remind, we need to fix more problems I found yesterday.
Oleg.
