My full test setup is post at
https://ask.fedoraproject.org/t/can-i-continue-incremental-send-after-subvol-is-split/14597?u=sampsonf
In short:
1. create a new subvol A
2. create 8 new files in A
3. create readonly snapshot as A0
4. send over by btrfs send /source/A0 | btrfs receive .
5. split A into two subvols A & B, and move 4 files over
A/file1-file4
A/B/file5-file8
6. create readonly snapshot. A as A10 & B as B10
7. send A10 over by btrfs -p A1 A10
8. send B10 over by btrfs -c A1 B10, then error
Why was that? What is the most efficient way to send over B10?

Typos in 7 & 8. Should be:
7. send A10 over by trfs -p A0 A10
8. send B10 over by btrfs -c A0 B10, then error
