    NFSv4: Fix the case where NFSv4 renewal fails
    
    If the asynchronous lease renewal fails (usually due to a soft timeout),
    then we _must_ schedule state recovery in order to ensure that we don't
    lose the lease unnecessarily or, if the lease is already lost, that we
    recover the locking state promptly...

    nfs: fix build error in nfsroot with initconst
    
    fix build error with latest kbuild adjustments to initconst.
    
    The commit a447c0932445f92ce6f4c1bd020f62c5097a7842 ("vfs: Use
    const for kernel parser table") changed:
    
        static match_table_t __initdata tokens = {
    to
        static match_table_t __initconst tokens = {
    
    But the missing const causes powerpc to fail with latest
    updates to __initconst like this:
    
    fs/nfs/nfsroot.c:400: error: __setup_str_nfs_root_setup causes a section type conflict
    fs/nfs/nfsroot.c:400: error: __setup_str_nfs_root_setup causes a section type conflict
    
    The bug is only present with kbuild-next.
    Following patch has been build tested.

    XPRTRDMA: fix client rpcrdma FRMR registration on mlx4 devices
    
    mlx4/connectX FRMR requires local write enable together with remote
    rdma write enable. This fixes NFS/RDMA operation over the ConnectX
    Infiniband HCA in the default memreg mode.
