I would move the 'also' - E.G. 'Some libraries need to also have OCF enabled'

How likely is it that this patch will work for a random kernel version?
>From the tarball I see a bunch of patches for different versions, so we
probably need something smarter than just hardcoding 3.2.1 - Perhaps
just an option where the user can type the version number of the patch
they want to use?
