From 31979008fdae72d7441643f3a5b1bdaedf481335 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Mon, 18 Jul 2016 16:06:03 +0200 Subject: [PATCH] lpfc: call lpfc_sli_validate_fcp_iocb() with the hbalock held Call lpfc_sli_validate_fcp_iocb() with the hbalock held, as the pointer to iocbq is not guaranteed to still be valid after looking it up.
