This was caused by any commit containing entries large enough to _always_ force a compaction. This would cause littlefs to think that it would need to split infinitely because there was no base case. The fix here is pretty simple: treat any commit with only a single entry as unsplittable. This forces littlefs to first try overcompacting (fitting more in a block than what has optimal runtime), and then failing that return LFS_ERR_NOSPC for higher layers to handle. found by TheLoneWolfling
