Message-Id: <200807242135.02363.bzolnier@gmail.com>
Date: Thu, 24 Jul 2008 21:35:02 +0200
From: Bartlomiej Zolnierkiewicz <bzolnier@...il.com>
To: linux-ide@...r.kernel.org
Cc: linux-kernel@...r.kernel.org
Subject: [PATCH 1/4] move HDIO_* ioctls support from <linux/hdreg.h> to <linux/hdio_ioctls.h>
Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@...il.com>
---
* against previous ATA_ID_*, ATA_CMD_* and ATA_* patchsets
* yes, this one also lacks proper description aka patch #0/0
but it is the last one so it is not worth doing it now ;)
