Subject: [PATCH] udiskslinuxfilesystem: Force native tools for mounted XFS fs
 size retrieval

Just another quirk discovered by Cockpit tests. Looks like
the superblock gets written on-disk at some later point while
the mounted filesystem structures keep the new geometry in-memory.
This is an obvious limitation of blkid that only reads data
from the block device.
