From: Steve Dickson <SteveD@xxxxxxxxxx>
The V4ROOT flag is supposed to make it safe to export filesystems that
would not ordinarily have been exported, by severely restricting which
directories on the filesystem may be accessed.
Before exporting those filesystems, we must have a way for userspace
(mainly mountd) to know whether the kernel supports the new flag. The
kernel has always silently ignored unknown export flags.
So, we bump the export version to signal mountd that the kernel has
pseudo root support.
