Treat it as\ndelta[1]=1 to work around these legacy mkfs versions.\n\n`lclusterbits > 14` is illegal for compact indexes, error out too.\n\ud83d\udccf Published: 2024-12-27T13:50:20.909Z\n\ud83d\udccf Modified: 2025-01-23T17:00:44.827Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/75a0a6dde803e7a3af700da8da9a361b49f69eba\n2. https://git.kernel.org/stable/c/f466641debcbea8bdf78d1b63a6270aadf9301bf\n3. https://git.kernel.org/stable/c/480c6c7b55aeacac800bc2a0d321ff53273045e5\n4. https://git.kernel.org/stable/c/daaf68fef4b2ff97928227630021d37b27a96655\n5. https://git.kernel.org/stable/c/0bc8061ffc733a0a246b8689b2d32a3e9204f43c", "creation_timestamp": "2025-01-23T17:02:58.000000Z"}
