Hello, Here is a patch updating make-bcache to disallow stray superblocks, so that it matches the stricter udev check. - https://github.com/g2p/bcache-tools/commits - https://github.com/g2p/bcache-tools/commit/master >From the commit message: Fail if the device has any leftover superblock or partition table label. Add a --wipe-bcache flag to overwrite bcache superblocks and recommend wipefs for non-bcache superblocks. Once the device is safe to write, always zero immediately before the bcache superblock. Make sure errors go to stderr. Use pkg-config. -- 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
