Not at all. Actually, I am interested in how much memory will be used when a driver is loaded into kernel. You know sometimes a lot of memory will be allocated at initialization phase when a driver is loaded into kernel.
I wonder if there is a method to check how much memory will be used when a driver is loaded into kernel directly and conviently.

There is no such method. You load the driver and recalculate slab/vmalloc/percpu stats.

Exactly. It is the only way that we can do currently.
