Subject: [PATCH 4/4] INIT_SIGHAND: use SIG_DFL instead of NULL
Date: Mon, 10 May 2010 21:51:04 +0200 [thread overview]
Message-ID: <20100510195104.GE5249@redhat.com> (raw)
In-Reply-To: <20100510194917.GA5249@redhat.com>
Cosmetic, no changes in the compiled code. Just s/NULL/SIG_DFL/ to make
it more readable and grep-friendly.
Note: probably SIG_IGN makes more sense, we could kill ignore_signals().
But then kernel_init() should do flush_signal_handlers() before exec().
