The logic to me seems correct.
However my fear is that a 16MB boundary is too low. I would felt
better with a round-up to 128MB. So the stripe size would vary from
128MB to 1GB in step of 128MB. The combination wouldn't be too high.

Hi All,
the following patches implement the recursively snapshotting and
deleting of a subvolume.
To snapshot recursively you must pass the -R switch:
# btrfs subvolume create sub1
Create subvolume './sub1'
# btrfs subvolume create sub1/sub2
Create subvolume 'sub1/sub2'
# btrfs subvolume
Move some code from cmd_subvol_show() to get_root_info(). This is
a preparation for the introducing of traverse_list_subvol_rec()
function.

can keep having checksums and the ability for raid 1 to repair those

I am trying to understand the pros and cons of turning this bit
