The tree field of struct extent_state was only used to figure out if
an extent state was connected to an inode's io tree or not. For this
we can just use the rb_node field itself.
On a x86_64 system with this change the sizeof(struct extent_state) is
reduced from 96 bytes down to 88 bytes,

Hi Qu
On 07/04/2014
If we do the following:
# mkfs.btrfs -f dev
# mount dev mnt
# dd if=/dev/urandom of=mnt/data bs=1M count=100
# umount dev
# btrfstune -S 1 dev --- make seeding device
# mount dev mnt
# btrfs dev add -f dev2 mnt
# umount dev
The new option -f will force to do dangerous changes.
e.g. clear the seeding flag.

When btrfs-image run on a mounted filesystem,
the undergoing fs operations may change what you have imaged a while ago.
In this case, give a warning to remind the user that he may not
get a consistent image he wants.

how are qgroups accounted for? Are they specifially tied to one

Qgroup implementation is aslo a little confusing for me at first:-) .
Yes, a qgroup is created automatically tied to one subvolume on creation
