From 982ab128dcf8b77bc18df74a83ffa70bcd59ccd3 Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 12 Mar 2019 16:30:10 -0700 Subject: scsi: lpfc: Fix lpfc_nvmet_mrq attribute handling when 0 Currently, when lpfc_nvmet_mrq is 0 it could mean 2 different things depending on when its looked at. If at module load time it specifies the default number of hardware queues to allocate, with 0 meaning default to the number of CPUs. But post module load, a value of zero means to disable mrq use. Changed the driver so that enablement of mrq is based on whether nvme target mode is enabled or not. When enabled, mrq is enabled. Thus, the cfg_nvemt_mrq field only specifies the number of mrq queues to enable, with 0 defaulting to the number of cpus.
