Subject: [Qemu-devel] [PATCH] block/nfs: Check for NULL server part
Date: Mon, 5 May 2014 20:27:49 +0200 [thread overview]
Message-ID: <1399314469-14211-1-git-send-email-mreitz@redhat.com> (raw)
After the URL has been parsed make sure the server part is valid in
order to avoid a segmentation fault when calling nfs_mount().
