Using a kernel that you know works perfectly well and backporting a few specific changes/fixes into it is an entirely reasonable thing to do.
replacing an entire file-system driver with one that's about 5 or 6 kernel versions newer is not "backporting a few specific changes/fixes". it's not a trivial change, and there's a good chance that fixes/changes in the new btrfs rely on other fixes and changes in the rest of the kernel. worse, you have a kernel+btrfs combo that's unique - which means difficult for anyone else to help you debug or even duplicate any problem, because nobody else has the exact same combination of code, so reporting bugs is almost useless. this is not just a btrfs issue, it's a general problem with backporting instead of upgrading. sometimes it's worth doing anyway - but as a last resort, when there are no other good or reasonable options. craig -- craig sanders <cas@taz.net.au>
