[parted-devel] [PATCH 3/6] partprobe: remove partitions when there is no PT

[Petr Uzel]

When partprobe does not detect any partition table on the device,
it should tell kernel to drop partitions on that device, but it
does not. Fix it.

* parted/partprobe.c (process_dev): Drop partitions even if no
partition table has been detected on the disk.
