H A D | xattr.c | 3c3b04d1 Wed Mar 25 13:26:41 CDT 2015 David Sterba <dsterba@suse.cz> btrfs: don't accept bare namespace as a valid xattr
Due to insufficient check in btrfs_is_valid_xattr, this unexpectedly works:
$ touch file $ setfattr -n user. -v 1 file $ getfattr -d file user.="1"
ie. the missing attribute name after the namespace.
