From ea3e2e72eeb3e8a9440a5da965914f9b12088626 Mon Sep 17 00:00:00 2001 From: Yi Zou Date: Tue, 30 Nov 2010 16:19:25 -0800 Subject: [PATCH] [SCSI] libfc: fix exchange being deleted when the abort itself is timed out Should not continue when the abort itself is being timeout since in that case the exchange will be deleted and relesased. We still want to call the associated response handler to let the layer, e.g., fcp, know the exchange itself is being timed out.
