[pve-devel] [PATCH storage v4 12/12] plugin: file_size_info: don't ignore base path with whitespace

[Dominik Csapak <d.csapak@proxmox.com>]

if the base image (parent) of an image contains whitespace in it's path
(e.g. a space), the current untainting would not match and it would seem
there was no parent.

Fix that by adapting the untaint regex
