Message-ID: <20061020005837.GX29920@ftp.linux.org.uk>
Date: Fri, 20 Oct 2006 01:58:37 +0100
From: Al Viro <viro@....linux.org.uk>
To: Linus Torvalds <torvalds@...l.org>
Cc: Alexey Dobriyan <adobriyan@...il.com>,
linux-kernel@...r.kernel.org, linux-arch@...r.kernel.org
Subject: Re: dealing with excessive includes
More interesting: skbuff -> highmem. That's a preliminary patch, needs
testing on more targets.
