Message-ID: <20070801161932.GA15959@havoc.gtf.org>
Date: Wed, 1 Aug 2007 12:19:32 -0400
From: Jeff Garzik <jeff@...zik.org>
To: Andrew Morton <akpm@...ux-foundation.org>,
Linus Torvalds <torvalds@...ux-foundation.org>
Cc: linux-ide@...r.kernel.org, LKML <linux-kernel@...r.kernel.org>
Subject: [git patches] libata fixes
The only notable: GregKH wanted the pci_reenable_device() change
associated with ata_piix to go in before the release, to avoiding
release with an imperfect API.
Please pull from 'upstream-linus' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev.git upstream-linus
