From 18d3d72a42a846d46b71131982c51d63eba2b7b3 Mon Sep 17 00:00:00 2001 From: Jeff Skirvin Date: Fri, 4 Mar 2011 14:06:38 -0800 Subject: isci: isci_request_cleanup_completed_loiterer checks task before task_done In the condition where outstanding I/Os are being cleaned from the device requests in process list, the cleanup function needs to check that the request is actually a sas-task and not a task management function.
