   We never needed that in our case. But yes, would be trivial. The question

Yes.  The default should be (RPC_DEF_SLOT_TABLE - 1), and the maximum should
be max(xprt_udp_slot_table_entries, xprt_tcp_slot_table_entries) (maybe
minus one).

I wonder if it would make sense to adjust NFS_MAX_READAHEAD when
xprt_*_slot_table_entries is changed via sysctl.
