Message-Id: <200801262043.17739.bzolnier@gmail.com>
Date: Sat, 26 Jan 2008 20:43:17 +0100

Cc: linux-ide@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [git patches] IDE updates part #2
IDE updates continued:
* make remaining built-in only IDE host drivers modular and cleanup ide.c
#ifdef hell (me)
* "resurrected" fixes for HDIO_DRIVE_TASKFILE ioctl (Tejun Heo)
* unify handling of REQ_TYPE_ATA_CMD and REQ_TYPE_ATA_TASKFILE requests
(me, heavily based on the earlier patches from Tejun Heo)
* host driver specific fixes: sl82c105, cs5520, cy82c693, atiixp and others
* the usual cleanups/fixups all over the place
All patches included in this update have been in IDE tree since at least 12th
December, got testing in -mm and (almost all) have been reviewed by Sergei
(IOW it is just another "boring" IDE update ;).
Linus, please pull from:
master.kernel.org:/pub/scm/linux/kernel/git/bart/ide-2.6.git/
