kindly note
The patch-set in this email-thread is now obsolete,
since a newer patch-set[1] based on the git repo at
git://repo.or.cz/btrfs-progs-unstable/devel.git for-chris
has been submitted which IMO is easy and good for integration.

This is an attempt to make btrfs cli more end user friendly.
And adds show subcommand to display all known (as of now)
information of the given subvol including its snapshot(s).
The below patch:
"Btrfs-progs: accommodate different layout for printing subvol list"
obsoletes the previosuly submitted patch
"Btrfs-progs: make provision to print subvol list tree format"
Please provide your review comments. Thanks.
An example output:
First list out all the subvols/snapshots using the list subcommand.
btrfs su list /btrfs
ID 256 gen 10 top level 5 path sv1
ID 259 gen 6 top level 5 path sv1/snap
ID 260 gen 7 top level 5 path snap
ID 261 gen 8 top level 5 path sv2
ID 262 gen 9 top level 5 path sv1/snap2
ID 263 gen 10 top level 5 path sv1/snap3
Then use show subcommand to know all known information about the
given subvol.
btrfs su show /btrfs/sv1
/btrfs/sv1
uuid: 508b12a5-ed2a-3942-af63-830967201070

Snapshot(s):

Uses a more simple approach to obtain the snapshots.
