Date: Thu, 30 Dec 2010 06:45:35 -0600 From: Robin Holt <holt@....com> To: David Rientjes <rientjes@...gle.com> Cc: Andrew Morton <akpm@...ux-foundation.org>, Ingo Molnar <mingo@...e.hu>, Greg KH <gregkh@...e.de>, "David S. Miller" <davem@...emloft.net>, Jens Axboe <axboe@...nel.dk>, linux-arch@...r.kernel.org, linux-kernel@...r.kernel.org Subject: Re: [patch 1/8] init: rename CONFIG_EMBEDDED to CONFIG_EXPERT Doesn't this patch series break the 'bisectable' rule for patches? I think you can get by with adding a CONFIG_EXPERT selects CONFIG_EMBEDDED in the first patch and the last patch removing that same selects.
