Re: BUG: Link from sub volume, then remove the subvolume -> wrong link

Hi,

I think message:'Operation not permitted' is more
proper for this problem than 'Invalid cross-device
link' simply because this link is not cross-device
link.

Of course, this operation is prohibited not by security
policy but by inner limitation of btrfs, this usage of
EPERM may be a kind of abuses...

Regards,
taruisi
