[Libguestfs] [PATCHv4 0/2] Introduce vfs_minimum_size API to get minimum filesystem size.

[Maxim Perevedentsev]

I have an issue with btrfs:

There's an API
 > btrfs inspect-internal min-dev-size /sysroot/

But this API is available only in btrfs-progs >= 4.2.
Before this, there's no reliable way to get minimum size (I could parse 
"btrfs filesystem show", but it is veeery inaccurate).

Can we require btrfs-progs v4.2? Or how should I work-around this issue?
