That changes it from assuming there are AT MOST 16 partitions to 
assuming there are AT LEAST 16 partitions.  I think you want to change 
the 16 to ped_disk_get_max_supported_partitions().

Actually, the patch I posted back on Jan 8 removed this function 
entirely, fixing a few problems with it.  It appears to not have been 
applied yet.

Resolves: rhbz#803108

* libparted/arch/linux.c (dm_reread_part_table): Use PED_MAX not PED_MIN
