The qla1280 can only cope with 32 bits, which is why all the macros have an _32. Over the years we've expanded the values in the SCSI command to be 64 bit but by and large, the truncation in this driver is silent. However, the correct fix should be to make the truncation explicit in the macro, so #define SCSI_LUN_32(Cmnd) ((int)Cmnd->device->lun) And the same for all the other _32 macros. This avoids the unexpected outcome that the _32 macros are actually returning 64 bits and cause me to do a WTF at your %lld change. James
