This also fixes an issue in Windows server 2016 failover cluster with

Interesting coincidence :) I only ran into this while looking at the
spec for the enable_pr change. Can you confirm that this fixes Win 2016
PR behaviour with an iblock / ifile backstore? If so I'll respin the
patch with an extra note in the commit message.

Cheers, David

Yes it fixes the "Storage Spaces Persistent Reservation" test in the Windows 2016 Server Failover Cluster validation suites when having many connections that result in more than 8 registrations. I tested your patch on 4.17 with iblock.
