Subject: [PATCH] libata: add FIXME above ata_dev_xfermask()
Date: Sat, 25 Mar 2006 11:14:07 +0900 [thread overview]
Message-ID: <20060325021407.GF5288@htj.dyndns.org> (raw)
In-Reply-To: <4424026A.1080504@pobox.com>
Add FIXME above ata_dev_xfermask noting that the current
implementation limits all transfer modes to the fastest of the slowest
device on a port which isn't necessary.
