[PATCH 0/2] fs: btrfs: add support for readdir

[Alexey Charkov]

Btrfs in U-boot currently uses a custom callback for ls and doesn't expose
the standard opendir/readdir/closedir interface, making it harder to use
in generic code. One area where this would be useful is in discovering BLS
type 1 entries [1] on a Btrfs filesystem.

Add support for the standard interface, and implement ls in terms of it.
