 >I think the issue is in the handling of DIOCGWEDGEINFO in dev/dm/device-mapper.c where it sets dkw->dkw_parent to dmv->name. Should that maybe also use device_xname(dmv->devt)? (and what should dkw->device_name be set to there?)
 
 
 Yes, the dm disk name was changed between -10 and -11 (from volume name
 to 'dm'+unit number). The same needs to be done for the DIOCWEDGEINFO
 code so that disk_find() can locate the disk structure in getdisksize().
