I can't test it now, I'm at work and have to look at other task, and ATM I don't have an instance with proper sources either... I'm currently running a mainline 3.15-rc3 kernel for Utopic (I'm on Ubuntu Trusty). I would love to give it a whirl during the weekend, though. Forgive me for being a rookie, but I'm not entirely sure which sources I should test this on. Is there a git branch specific to bcache? Or another specific kernel branch that I should use this on? Or would it just be any recent version (such as 3.15-rc3, which I kinda need for Java to work without oopsing).
