Subject: Re: error: invalid application of ???sizeof??? to
incomplete type ???struct text_poke_loc??? - kernel - 5.6.2
Hi,
Sorry for the late reply. I've been recently working on a big change in LKRG's
ED logic. I've just pushed it to the repo.
I will try to look into that issue as soon as I can. It looks like kernel devs
changed the JUMP_LABEL logic (again). I don't think Whonix fork can work under
such kernels as well.
Thanks,
Adam
