Sure! I never expected it to live outside the kernel tree as a separate
package, but I'm happy to accommodate for that.

I think that I'll just match the version number with the kernel version
since what mostly matters is what you have in kernel/lockdep.c, so for
example, right now we'll have 'liblockdep.so.3.15.0'. Sounds good?

Thanks,
Sasha
