This is fine for releasing the locks, but how do you plan to re-enter
the grace period for reclaiming the locks when you relocate the export?
And how do you intend to segregate the export for which reclaims are
valid from the ones which are not?  How do you plan to support the
sending of SM_NOTIFY?  This might be where a lockd per export has an
advantage.
