u can assume a kernel is a minimal core. after it start up, it support basic fucntions. when it need sth, it check and try to load the module dynamically. if succ, then u can consider the module is part of kernel now, even the speed of accessing the routines in module and in kenrel are the same. if fails, then u can not use that functions.
for example. u start up the linux and now u want to mount ntfs system or fdisk it, but ntfs is not in kernel. then kernel will check if there is a ntfs.o.if not, then fails. if so, kernel will load the ntfs.o and then u can use it. |
