[parted-devel] [PATCH] libparted: remove device mapper node for last partition

[Petr Uzel]

This patch fixes the situation when last partition is removed
on device-mapper. In such case, ped_disk_get_last_partition_num()
returns 0 (the last partition is already gone), so
_dm_remove_parts() is not called at all and device-mapper node for
the last partition is not removed.

* libparted/arch/linux.c (_dm_reread_part_table): Call
_dm_remove_parts() unconditionally.
