(zeroblock):
Change type to `void *'.
(diskfs_set_hypermetadata):
Use store_{read,write} instead of diskfs_device_{read,write}_sync.
(get_hypermetadata):
Cast ZEROBLOCK when vm_{de,}allocating.
Use DISKFS_DISK_NAME instead of DISKFS_DEVICE_ARG.
(get_hypermetadata, diskfs_readonly_changed):
Use fields in STORE instead of DISKFS_DEVICE_* variables.
