Subject: aic7xxx: Adjust .max_sectors
Date: Fri, 06 Oct 2006 09:22:41 +0200 [thread overview]
Message-ID: <45260441.1020102@suse.de> (raw)

Hi James,
the aic7xxx drivers do not set .max_sectors, and hence defaults to
512kB. The adaptec sources indicate that it in realiter can handle up to
4MB, so there is no reason not to adjust it.
Please apply,
Hannes

aic7xxx: Adjust .max_sectors
According to the adaptec sources aic7xxx / aic79xx really can do
4MB transfers. So we should adjust .max_sectors.
