svn commit: r359222 - projects/nfs-over-tls/sys/sys

[Rick Macklem]

Author: rmacklem

New Revision: 359222
URL: https://svnweb.freebsd.org/changeset/base/359222

Log:
  Hack around 32bit flags in the export_args structure by (re)defining
  the export flags under MNTEX_ instead of MNT_.
  It retains the bits already used, but allows others that are MNT_xxx
  bits not used in export_args to be defined for export_args.
  This might be a rasonable workaround?
