Issue is improper MACRO usage MEGASAS_IS_LOGICAL, which gives incorrect check condition in qcmd Path. Below is proposed fix. diff --git a/drivers/scsi/megaraid/megaraid_sas.h b/drivers/scsi/megaraid/megaraid_sas.h index 74c7b44..0d2625b 100644 --- a/drivers/scsi/megaraid/megaraid_sas.h +++ b/drivers/scsi/megaraid/megaraid_sas.h @@ -2236,7 +2236,7 @@ struct megasas_instance_template { }; #define MEGASAS_IS_LOGICAL(scp) \ - (scp->device->channel < MEGASAS_MAX_PD_CHANNELS) ? 0 : 1 + ((scp->device->channel < MEGASAS_MAX_PD_CHANNELS) ? 0 : 1) #define MEGASAS_DEV_INDEX(scp) \ (((scp->device->channel % 2) * MEGASAS_MAX_DEV_PER_CHANNEL) + \ > > Kashyap, have you tested the stable fix without the remainder of the driver > update in place? Martin - I validated whole series. Apologies for this. Please help me to know how to fix this ? Do I need to send only fix on top of latest commit (as posted above - MACRO definition) for this issue ? > > -- > Martin K.
