47 * This is the structure of the leaf nodes in the Btree.
48 *
49 * Struct leaf_entry's are packed from the top. Names grow from the bottom
50 * but are not packed. The freemap contains run-length-encoded entries
51 * for the free bytes after the leaf_entry's, but only the N largest such,
52 * smaller runs are dropped. When the freemap doesn't show enough space
53 * for an allocation, we compact the namelist area and try again. If we
54 * still don't have enough space, then we have to split the block.
55 *
56 * Since we have duplicate hash keys, for each key that matches, compare
57 * the actual string. The root and intermediate node search always takes
58 * the first-in-the-block key match found, so we should only have to work
59 * "forw"ard. If none matches, continue with the "forw"ard leaf nodes
60 * until the hash key changes or the filename is found.
61 *
62 * The parent directory and the self-pointer are explicitly represented
63 * (ie: there are entries for "." and "..").
64 *
65 * Note that the count being a __uint16_t limits us to something like a
66 * blocksize of 1.3MB in the face of worst case (short) filenames.
