[parted-devel] [PATCH 8/8] libparted: optimize _disk_sync_part_table

[Petr Uzel]

In _disk_sync_part_table, if the largest partition number (lpn) is
0, it does not make sense to go through the loops below. Return
immediately instead.

* libparted/arch/linux.c (_disk_sync_part_table): Return immediately
if lpn == 0.
