IMHO, strictly from module vs core kernel code perspective, there is no speed difference. The reason is, once the kernel is loaded, it is the kernel itself. So it is not separated into isolated segment or something like that. Yes module is loaded into vmalloc-ed memory area, but that's it. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
