Subject: [PATCH 03/60] driver core: Rearrange struct device for better packing
Date: Tue, 6 Jan 2009 14:11:22 -0800 [thread overview]
Message-ID: <1231279939-32728-3-git-send-email-gregkh@suse.de> (raw)
In-Reply-To: <20090106221123.GA32689@kroah.com>
From: Matthew Wilcox <matthew@wil.cx>
This minor rearrangement saves 16 bytes from sizeof(struct device)
according to pahole.
