root@xerus:~# mount -vo user_subvol_rm /dev/sdd4 /test
mount: wrong fs type, bad option, bad superblock on /dev/sdd4,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
root@xerus:~# dmesg | tail -2
[1514588.018991] BTRFS info (device sdd4): unrecognized mount option 'user_subvol_rm'
[1514588.028430] BTRFS: open_ctree failed
user_subvol_rm is not listed on
https://btrfs.wiki.kernel.org/index.php/Mount_options
Did you mean user_subvol_rm_allowed?
I have already used this option, without success. See above.
