From c1668948e8b74cd8f912054ba4412a1cbf0cd03c Mon Sep 17 00:00:00 2001 From: Christian Schoenebeck Date: Tue, 15 Mar 2022 11:08:33 +0100 Subject: [PATCH] tests/9pfs: Twalk with nwname=0 Send Twalk request with nwname=0. In this case no QIDs should be returned by 9p server; this is equivalent to walking to dot.
