How can I add lz4-patch to kernel?

[suhm]

Hi all,

i've seen this post here: http://forum.xbian.org/thread-2217-post-24363.html#pid24363

so there is a special xbian lz4-patch for the kernel. maybe this might be a solution to mount my btrfs partition on my normal ubuntu/debian/etc system?

My question here is:
can u guys give me a little "how to" / blue print for compiling/patching my standard ubuntu kernel with this patch?

PS: i've seen that the github-link in this post might be offline where can i find the right one?

thanks very much in advance!
