I got "btrfs receive" error when testing this, with 4.3-rc1 kernel and
btrfs-progs v4.2, not sure if this is expected
At subvol /mnt/testarea/scratch/mysnap2_ro
# /usr/bin/btrfs receive /mnt/testarea/scratch -f /mnt/testarea/test/btrfs-test-104/1.snap
At subvol mysnap1
# /usr/bin/btrfs receive /mnt/testarea/scratch -f /mnt/testarea/test/btrfs-test-104/2.snap
ERROR: unlink o258-7-0 failed. No such file or directory
At snapshot mysnap2_ro
failed: '/usr/bin/btrfs receive /mnt/testarea/scratch -f /mnt/testarea/test/btrfs-test-104/2.snap'
Thanks,
