Subject: [PATCH] signals: cleanup the usage of print_fatal_signal()
Date: Tue, 11 Mar 2008 00:17:44 +0300 [thread overview]
Message-ID: <20080310211744.GA1580@tv-sign.ru> (raw)
Move the callsite of print_fatal_signal() down, under
"if (sig_kernel_coredump(signr))", so we don't need to check signr != SIGKILL.
We are only interested in the sig_kernel_coredump() signals anyway, and due to
the previous changes we almost never can see other fatal signals here except
SIGKILL.
