Yes, and...? CIFS also doesn't have hardlinks, so _there_ d_find_alias() is just fine. 9P is actually trickier; there we need some massage, but for CIFS it's literally a matter of one function call. The problem with 9P is that the way we do it right now, you might pick the wrong dentry. _Some_ alias already bears the FID you are after, but if you end up picking the one that doesn't, you might very well end up being unable to obtain one either. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
