Why bother? If you have to use _mini() once, why not just use it
all the
time?
Because _mini() is for kernel space only, and this routine services
user-level pointers as well, I did not think that changing _mini()
was worth it.
Actually, instead of slab_is_available() we could have use something
like "have started init"() but I know of no such function.
