A rather humorous issue, we accidentally ended up mixing our file namespace with our superblocks. This meant if we created a file named "littlefs" it would reference the superblock and all sorts of things would break. Fixing this also highlighted another issue, the fact that the superblock always needs to come before any file entries in the directory. I didn't account for this in the initial B-tree design, but we need a higher ordering for superblocks + children + files than just name. To fix this I added ordering information in the 2 bits currently unused in the tag type. Though note that the size of these fields are flexible. 9-bit type field: [--- 9 ---] [1|- 3 -|- 2 -|- 3 -] ^ ^ ^ ^- type-specific info | | \------- ordering info | \------------- subtype \----------------- user bit
