From 1b34e97441384d527c438a6ee597bfc800373bce Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Sat, 25 Aug 2007 10:40:42 +0200 Subject: [PATCH] firewire: fw-sbp2: always enable IRQs before calling command ORB callback MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On IOMMU-less noncoherent architectures, orb->callback will memcpy the whole SCSI command buffer for READ-like SCSI commands. It is therefore friendlier to enable IRQs before the call, like before patch "Add ref-counting for sbp2 orbs".
