Just tried it - I can reproduce it, but it's gone in 3.6. Looks like a 3.5 bug, not a bcache bug. I'm gonna reset the master branch to my current dev branch soon as I've tested it a bit more, but I'd suggest the bcache-3.2 branch - that's the best tested code. -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
