Subject: Re: [PATCH] livepatch: introduce klp_func called interface

Hi Bros,

How about my patch? I do think it is a viable feature to show the state of the patched function. If we add an unlikely branch test before we set the 'called' state, once this function is called, there maybe no negative effect to the performance.

Please give me some advice.

Regards,
Wardenjohn
