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.

Thanks,
