From 23077f1d72d279244536f11db51258fc4759c81a Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Mon, 11 Sep 2006 20:17:14 +0200 Subject: ieee1394: sbp2: slightly reorder sbp2scsi_abort Put the target's fetch agent into reset state before the underlying ORB DMA is unmapped and the ->done handler is called. It is highly unlikely but the target could access that ORB right before sbp2 sends the reset request.
