Hi Josh,

By "(un)patching process" are you referring to the klp_patch at large or
each klp_object? ie, would all klp_objects execute their hooks before
anything is (un)patched? Just trying to clarify.

You're suggesting that post-(un)patch-hooks:

1 - Notify klp_objects when a KLP_(UN)PATCHED transition completes

and for subsequently loaded klp_objects (ie modules):

2 - On load - notify it with current KLP_(UN)PATCHED state,
Steady state - same as (1) above.
