Hi All, While going through the code in kernel/sys.c and include/linux/notifier.h , i came across notifier chains in kernel 2.6.20.1 . What are notifier chains exactly and why do we need them in the networking code? Is it a generic callback list? Or is it specific to the networking stack? Any help?
