Subject: [PATCH 5/6] lpfc 8.1.4 : Two misc fixes
Date: Tue, 07 Mar 2006 15:04:19 -0500 [thread overview]
Message-ID: <1141761860.25430.19.camel@localhost.localdomain> (raw)
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.
