I have a question about fb_mmap in uclinux2.4.
It (should) behave (almost) the same for uClinux and real Linux.
what is the usage of fb_mmap(struct file *file, struct vm_area_struct *vma) my kernel is arm7 no mmu , does the fb_mmap function do some help for my framebuffer driver if i use fb_mmap function?
