Subject: libfdisk: use fdisk_add_partition() for unused partno
X-Git-Tag: v2.29-rc1~253
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a3a125b9227be82d84941062feaf3ddfde8265f7;p=thirdparty%2Futil-linux.git

libfdisk: use fdisk_add_partition() for unused partno

For example:

   sfdisk -N <parno>

may address unused partition. In this case we need to redirect from
fdisk_set_partition() to fdisk_add_partition() and follow default
setting (used all free space).
