From a6a39ca1badbeafc16941fcf2c1010c8c65c8ddc Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Tue, 28 Jul 2009 14:44:05 -0700 Subject: [PATCH] ioat: fix self test interrupts If a callback is to be attached to a descriptor the channel needs to know at ->prep time so it can set the interrupt enable bit. This is in preparation for moving descriptor ioat2 descriptor preparation from ->submit to ->prep.
