[RFC PATCH 4/6] Btrfs-progs: add write and clone commands debug info to receive

[Howard McLauchlan <linux@hmclauchlan.com>]

From: Filipe Manana <fdmanana@gmail.com>

When specifying -vv print information about received write and clone commands too,
as we do this for other commands already and it's very useful for debugging and
troubleshooting.
