Reviewed-by: Sesidhar Baddela Reviewed-by: Arulprabhu Ponnusamy Signed-off-by: Karan Tilak Kumar --- Changes between v4 and v5: Incorporate review comments from Martin: Modify patch commits to include a "---" separator. Changes between v2 and v3: Incorporate review comment from Hannes: Modify FNIC_MAIN_DBG to prepend fnic number. Modify FNIC_MAIN_DBG definition to prepend function name and line number. Modify FNIC_FCS_DBG definition to prepend function name and line number. Replace FNIC_MAIN_DBG with FNIC_FCS_DBG in fnic_fcs.c Use fnic_num as an argument to FNIC_MAIN_DBG and FNIC_FCS_DBG. Host number is still used as an argument to FNIC_MAIN_DBG and FNIC_FCS_DBG since it in turn uses shost_printk. --- drivers/scsi/fnic/fnic.h | 12 ++++--- drivers/scsi/fnic/fnic_fcs.c | 63 +++++++++++++++++++---------------- drivers/scsi/fnic/fnic_main.c | 4 +-- drivers/scsi/fnic/vnic_dev.c | 4 +++ 4 files changed, 49 insertions(+), 34 deletions(-) diff --git a/drivers/scsi/fnic/fnic.h b/drivers/scsi/fnic/fnic.h index 721a31a03628..4dde8afbb69b 100644 --- a/drivers/scsi/fnic/fnic.h +++ b/drivers/scsi/fnic/fnic.h @@ -144,13 +144,17 @@ do { \ } while (0);
