From ace0829c0d08f0e5f1451e402e94495bc2166772 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Fri, 24 Apr 2020 15:35:16 +0200 Subject: [PATCH] virtiofsd: Show submounts Currently, setup_mounts() bind-mounts the shared directory without MS_REC. This makes all submounts disappear. Pass MS_REC so that the guest can see submounts again.
