From cbfb537eef7c531b596c3aecd947ee6920bea2d7 Mon Sep 17 00:00:00 2001 From: Bin Lu Date: Tue, 2 Jun 2020 22:55:31 -0400 Subject: Deleting the maxSendBufferSize from fs/host When I do high-performance networking, the value of wmem_max is often set very high, specially for 10/25/50 Gigabit NIC. I think maybe this restriction is not suitable.
