And apparently the project's GIT repo is an unreliable place to get the bug-fixed code because it's not being kept up to date. Until Kent et. al. remedies this procedural problem I would *only* use the 3.11.5 release and personally would be a bit circumspect in calling it fully production ready. I don't believe there are any known significant bugs but with the recent flurry of fixes I'd liken it's solidity as more pudding rather than cake. -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
