From 9b2556fa5364673ee5918cef63370b31b0fe957b Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 27 Nov 2014 06:46:12 -0500 Subject: [PATCH] xprtrdma: Increase default credit limit [ Queued for upstream v4.3 ] In preparation for similar increases on NFS/RDMA servers, bump the advertised credit limit for RPC/RDMA to 128. This allocates some extra resources, but the client will continue to allow only the number of RPCs in flight that the server requests via its advertised credit limit.
