Simple question for comment in btrfs-progs qgroup code

[Sidong Yang]

Hello!

I see an comment in qgroup cmds below.

diff --git a/cmds/qgroup.c b/cmds/qgroup.c
index 2da83ffd..a71089e9 100644
--- a/cmds/qgroup.c
+++ b/cmds/qgroup.c
@@ -84,6 +84,7 @@ static int _cmd_qgroup_assign(const struct cmd_struct
*cmd, int assign,
        /*
        * FIXME src should accept subvol path
        */

This comment is little confusing for me. src was parsed with
parse_qgroupid() and it also accepts subvol path. is it outdated
comment? or src should accept only lowest level of qgroup?

Thanks,
Sidong
