Subject: [PATCH 40/69] partprobe: remove partitions when there is no partition
|
|
table
|
|
|
|
When partprobe detects no partition table on a device, it should
|
|
tell the kernel to drop partitions on that device, but it did not.
|
|
* parted/partprobe.c (process_dev): When ped_disk_probe fails,
|
|
create a dummy (empty) partition table and use that.
|
|
* NEWS (Bug fixes): Mention it.
