We've noticed, that nfs mounts with vers=4.0 do not pick up a updated lease_time after a restart of the nfs server. This was discussed in the thread "4.0 client and server restart with decreased lease time" on linux-nfs [1]. This patch set fixes the issue for nsf4.0 clients so that hey behave as nfs4.1 and nfs4.2 clients do. After a new clientID is established, the lease_time is re-fetched and used. I've notcied, that the flag NFS_CS_CHECK_LEASE_TIME is not functional in the existing code. It is set and tested, but never reset. Either nfs4_setup_state_renewal should reset the flag after it verified the lease_time or the flag could be removed altogether. I left it as is, because I don't known what is preferred.
