I'm saying that neither of those are in the kernel _anywhere_ now, so if someone's adding them the sensible thing seems to be to add them to the crypto api, access them through it, and then if we ever add more we get them for free on the btrfs side instead of needing to reinvent the wheel every time. In short, there's a place for hashes - why not use it? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
