It's in use as a mount point. You need to unmount it first. -- You are receiving this mail because: You are on the CC list for the bug.

The -o subvolid=0 mounts the "true" root of the file system instead of the default subvolume, so you can see the entire namespace. -- You are receiving this mail because: You are on the CC list for the bug.
