V2: Make sure, code doesn't depend on CONFIG_NFS_V4_1. I've scattered
#endifs and #ifdefs into the source instead of moving code into other
areas to be more friendly to git. Tell me if you prefer otherwise.
Currently, 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.
Tested with
CONFIG_NFS_V4=m CONFIG_NFS_V4_1=y CONFIG_NFS_V4_2=y : mount
CONFIG_NFS_V4=m CONFIG_NFS_V4_1=y CONFIG_NFS_V4_2=y : mount vers=4.0
CONFIG_NFS_V4=m CONFIG_NFS_V4_1=y CONFIG_NFS_V4_2=n : mount
CONFIG_NFS_V4=m CONFIG_NFS_V4_1=y CONFIG_NFS_V4_2=n : mount vers=4.0
CONFIG_NFS_V4=m CONFIG_NFS_V4_1=n CONFIG_NFS_V4_2=n : mount
and several restarts of the nfs server with changed leases times, which
were picked up by the client.
