[PULL 4/6] virtiofsd: Show submounts

From: Dr. David Alan Gilbert (git)
Subject: [PULL 4/6] virtiofsd: Show submounts
Date: Fri, 1 May 2020 20:14:58 +0100

From: Max Reitz <address@hidden>

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.
