18 * Size of a block or zone (data allocation unit on disk)
24 * General layout: all have one boot block, one super block and
27   all the block numbers (including the super block) are offset by one track.
56       There is a cache of a certain number of free inodes in the super-block.
59 * Free block management:
63       since it is not true that every free block contains a pointer to
64       the next free block. Rather, the free blocks are organized in chunks
65       of limited size, and every now and then a free block contains pointers
67       contains pointers and so on. The list terminates with a "block number"
68       0 on Xenix FS and SystemV FS, with a block zeroed out on Coherent FS.
70 * Super-block location:
71   - Minix FS     block 1 = bytes 1024..2047
72   - Xenix FS     block 1 = bytes 1024..2047
74   - Coherent FS  block 1 = bytes 512..1023
76 * Super-block layout:
143                1 indirect block (pointers to blocks)
144                1 double-indirect block (pointer to pointers to blocks)
147                1 indirect block (pointers to blocks)
148                1 double-indirect block (pointer to pointers to blocks)
149                1 triple-indirect block (pointer to pointers to pointers to blocks)
151 * Inode size, inodes per block
165 * Dir entry size, dir entries per block
178 Notation: We often speak of a "block" but mean a zone (the allocation unit)
179 and not the disk driver's notion of "block".
