94  * A full indirect block use supports 512 x 128-byte blockrefs in a 64KB
99  * using 64KB indirect blocks (128 byte refs, 512 or radix 9 per indblk).
128  * HAMMER2_SEGSIZE	- Allocation map segment size, typically 4MB
168  * Indirect blocks are typically either 4KB (64 blockrefs / ~4MB represented),
169  * or 64KB (1024 blockrefs / ~64MB represented).
189  * A 4MB segment is reserved at the beginning of each 2GB zone.  This segment

194  * 4MB = 64 x 64K blocks.  Each 4MB segment is broken down as follows:
198  *  1 freemap00 level1 FREEMAP_LEAF (256 x 128B bitmap data per 1GB)
199  *  2           level2 FREEMAP_NODE (256 x 128B indirect block per 256GB)
200  *  3           level3 FREEMAP_NODE (256 x 128B indirect block per 64TB)
201  *  4           level4 FREEMAP_NODE (256 x 128B indirect block per 16PB)
202  *  5           level5 FREEMAP_NODE (256 x 128B indirect block per 4EB)
266  * (256 x struct hammer2_bmap_data).  Each structure represents 4MB of storage
293  *	     (i.e. a multiple of 4MB).  VOLUME_ALIGN must be >= ZONE_SEG.
366  * Freemap radix.  Assumes a set-count of 4, 128-byte blockrefs,

448  * Two linear areas can be reserved after the initial 4MB segment in the base
546  * WARNING!  This structure must be exactly 128 bytes long for its config
603  * media topology recursion.  This 128-byte data structure is embedded in the

751  * types >= 128 are pseudo values that should never be present on-media.
860  * Each 128-byte entry contains the bitmap and meta-data required to manage
