Package: btrfs-progs
Version: 4.16.1-2
Severity: normal

btrfs-progs 4.16.1 introduced a regression in btrfs send.  After
creating a snapshot of / in /var/backups, I've sent an incremental
stream to a filesystem mounted on /backups:

% btrfs subvolume snapshot -r / /var/backups/weekly-20180517T123915Z
Create a readonly snapshot of '/' in '/var/backups/weekly-20180517T123915Z'

% btrfs send -p /var/backups/monthly /var/backups/weekly-20180517T123915Z | 
btrfs receive /backups
ERROR: not on mount point: /
ERROR: empty stream is not considered valid

In the pipeline above, btrfs send always fails with "ERROR: not on mount
point: /".

The problem seems to be related to bug

Pull request should fix
this regression.
