Package: btrfs-progs
Version: 4.20.1-1
Severity: important

'btrfs send' stopped working starting with 4.20.1-1.

To reproduce, create a snapshot of / in a directory that is part of the root FS:

  % btrfs subvolume snapshot -r / /var/backups/daily-20190130T065412Z
  Create a readonly snapshot of '/' in '/var/backups/daily-20190130T065412Z'

'btrfs send' from btrfs-progs 4.20.1-1 then fails, thus making it
impossible to send snapshots to other filesystems:

  % btrfs send /var/backups/daily-20190130T065412 > /dev/null
  ERROR: failed to determine mount point for 
/var/backups/daily-20190130T065412Z: No such file or directory
