Hello

We are using libguestfs with nested partitions: One partition
encrypted with LUKS include a GPT and several partition.
In order to make the nested partition available to the system after
the cryptsetup-open, partprobe need to be run.
I guess it is true for all kind of nested partitions (encrypted or not).

This patch add a partprobe call in the API.

Regards

Philippe

The patch is fine as far as it goes, but you'll need to include the
new partprobe.c file :-)
