partutil.c::getdiskinfo to use it to get disk geometry info.
Use DIOCGWEDGEINFO ioctl to get information about partition size, if disk
driver doesn't support it use old DIOCGDINFO. This patch adds support for
wedge like devices(lvm logical volumes, ZFS zvol partitions) to newfs and
other tools.
No objections on tech-userlevel@.
so that we don't run multiple fsck's on the same spindle at the same time!
- Add some partition getting utilities that are wedge aware (soon to be able
to use the native geometry ioctl), so that we can fsck wedges.
