The option parser in the btrfs utility is going to be updated and will accept arguments in a stricter form, namely that options must come before their non-option argument. Otherwise eg. the -f option in send would be understood as another path and not an option leading to many test failures. The canonical form should be: btrfs command subcommand [-options] [arguments] Signed-off-by: David Sterba <dsterba@suse.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>
