From 29fba38b793225798104a1ac870e6807ebd078dd Mon Sep 17 00:00:00 2001 From: Benny Halevy Date: Wed, 1 Apr 2009 09:22:44 -0400 Subject: [PATCH] nfs41: lease renewal Send a NFSv4.1 SEQUENCE op rather than RENEW that was deprecated in minorversion 1. Use the nfs_client minorversion to select reboot_recover/ network_partition_recovery/state_renewal ops. Note: we use reclaimer to create the nfs41 session before there are any cl_superblocks for the nfs_client.
