Subject: [PATCH 00/11] cleanup/fix allow_signal/disallow_signal
Date: Sun, 23 Mar 2014 20:37:30 +0100 [thread overview]
Message-ID: <20140323193730.GA10464@redhat.com> (raw)
Hello.
allow_signal() and disallow_signal() have the very strange (wrong
actually) semantics. They mix/confuse "sigprocmask" and "sigaction"
logic.
This series tries to cleanup and fix them, plus other (mostly related)
cleanups.
Oleg.
