From daa142d1773dd3a986f02a8a4da929608d24daaa Mon Sep 17 00:00:00 2001 From: Brian King Date: Tue, 20 Apr 2010 14:21:35 -0500 Subject: [PATCH] [SCSI] ibmvfc: Reduce error recovery timeout If a command times out resulting in EH getting invoked, we wait for the aborted commands to come back after sending the abort. Shorten the amount of time we wait for these responses, to ensure we don't get stuck in EH for several minutes.
