From a4699f5647f369e8ab7ec56b7cd98580c933c3f3 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 30 Oct 2017 16:21:49 -0400 Subject: [PATCH] xprtrdma: Put Send CQ in IB_POLL_WORKQUEUE mode Lift the Send and LocalInv completion handlers out of soft IRQ mode to make room for other work. Also, move the Send CQ to a different CPU than the CPU where the Receive CQ is running, for improved scalability.
