Subject: [PATCH 4/5] virtiofsd: Open lo->source while setting up root in sandbox=NONE mode
Date: Wed, 29 Jul 2020 18:14:09 -0400 [thread overview]
Message-ID: <20200729221410.147556-5-vgoyal@redhat.com> (raw)
In-Reply-To: <20200729221410.147556-1-vgoyal@redhat.com>
In sandbox=NONE mode, lo->source points to the directory which is being
exported. We have not done any chroot()/pivot_root(). So open lo->source.
