From fc6c12bcc19bdff6b4bcb02f5bd6d9fa59a7e1af Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 7 Mar 2006 15:04:19 -0500 Subject: [PATCH] [SCSI] lpfc 8.1.4 : Two misc fixes Two misc fixes: - Fix deadlock caused by return with host_lock held in lpfc_findnode_did - Initialize all fields of the allocated mail box structure to zero. Was causing some sysfs mailbox commands to fail immediately after load.
