From f1d7fb7a8ab55357b6c7d44a53f644a043680ed1 Mon Sep 17 00:00:00 2001 From: Brian King Date: Thu, 18 Jun 2009 09:06:52 -0500 Subject: [PATCH] ibmvfc: Process async events before command responses Since async events could indicate changes to link status, or events which could affect decisions made during discovery, we should process async events prior to command completion responses.
