Message-Id: <200904022209.32603.bzolnier@gmail.com>
Date: Thu, 2 Apr 2009 22:09:31 +0200
From: Bartlomiej Zolnierkiewicz <bzolnier@...il.com>
To: Linus Torvalds <torvalds@...ux-foundation.org>
Cc: linux-kernel@...r.kernel.org
Subject: [git pull] <linux/hdreg.h> cleanups
Hi,
I still have some leftover (non-IDE & non-libata) patches from the last
summer converting all struct hd_driveid & co. users to use <linux/ata.h>
explicitly and cleaning <linux/hdreg.h> accordingly.
Original patches still apply just fine to the current Linus' tree (I also
made sure that there are no potential conflicts/breakages caused by new
users of <linux/hdreg.h>) and the whole patchset is now available in the
form of git tree here:
http://git.kernel.org/?p=linux/kernel/git/bart/linux-hdreg-h-cleanup.git
I haven't heard a single complaint about them so it seems like everybody
is happy with them and thus it would be nice to get them merged. :)
Linus, please consider pulling from:
master.kernel.org:/pub/scm/linux/kernel/git/bart/linux-hdreg-h-cleanup.git/
to receive the following updates:
