The kexploit has nothing to do with triggering the IOSU exploit.Frist. The kernels exploits are not ilimited.
Second. Trust me, when IOSU release, it will be more easy program apps, and once IOSU exploit get load, you don't have to go to the browser each time you launch a homebrew apps.. I think all devs need aim to that..
If he release it now, N release a 5.5.2 version, patching the exploit and that's all.. It will only work to give loadiine in 5.5 and 5.5.1.. No more k exploits please.. Save it for trigger a IOSU hack
