Subject: [Patch -v4 3/4] checkpatch.pl the new kernel/reboot.c file.
Date: Tue, 16 Apr 2013 05:01:46 -0500	[thread overview]
Message-ID: <20130416100146.GL3672@sgi.com> (raw)
In-Reply-To: <20130416095641.GL3658@sgi.com>


I did allow the remaining 81 character line behind.  It did not seem
like it was worth changing.  Otherwise, it now passes checkpatch.pl.
