Howdy,
If you remove an existing directory and then create a subvolume with the
same name the incremental send (btrfs send -p) will die with errno==2
(file not found).
Steps to Reproduce:
btrfs subvol create scratch # make a playground
mkdir scratch/example
btrfs subvol snap -r scratch scratch_BEFORE
rmdir scratch/example
btrfs subvol create scratch/example
btrfs subvol snap -r scratch scratch_AFTER
btrfs send -p scratch_BEFORE scratch_AFTER >/dev/null
The output produced:
At subvol scratch_AFTER
ERROR: send ioctl failed with -2: No such file or directory
