But I'm sure we can find a solution for that. I started a branch with an alternative for if KERNEL_VERSION. Please see: http://linuxtv.org/hg/~mchehab/backport/ Basically, it has some perl rules that identifies the points on the source code where an KABI function has changed and dynamically patches the code. On my tests, this strategy works fine, but I haven't finished removing all KERNEL_VERSION checks from the code. If someone is interested, please be my guest fixing the code and improving it.
