Load/unload hooks will be useful to have when applying livepatches. Today one can create hooks by writing code in the livepatch init/exit functions and properly setting up module notifier callbacks to handle various cases. This can be error prone and unwieldy as we have the proper mechanisms already in the livepatch proper code. I've tested this code with some sample livepatch code that exercised the following: - works with single/multiple hooks for both load/unload - works if load_hooks/unload_hooks are NULL - works if individual hooks are NULL - handles bad return values from hooks - handles properly when inserting/removing dependent modules - can handle load_hook for vmlinux as well The idea of these hooks are based off of the kpatch project.
