9  * note: file system in transition to aggregate/fileset:
11  * file system mount is interpreted as the mount of aggregate,
13  * the aggregate;
15  * a file system/aggregate is represented by an internal inode
16  * (aka mount inode) initialized with aggregate superblock;
19  * (an aggregate itself is structured recursively as a filset:
21  * allocation map inode" (aka aggregate inode) where each inode
23  * on-disk inode in uniform way at both aggregate and fileset level;
28  * per aggregate information, e.g., block size, etc.) as well as
31  *   aggregate
33  *   mntvfs -> fileset ipimap+ -> aggregate ipbmap -> aggregate ipaimap;
98 	 * initialize aggregate inode allocation map
106 	 * open aggregate block allocation map
119 	 * initialize aggregate block allocation map
127 	 * open the secondary aggregate inode allocation map
129 	 * This is a duplicate of the aggregate inode allocation map.
