From f4434529003522d72b314d26d65b18c06ea9307c Mon Sep 17 00:00:00 2001 From: Maor Gottlieb Date: Tue, 23 Jun 2020 14:30:36 +0300 Subject: [PATCH] RDMA: Add dedicated MR resource tracker function In order to avoid double multiplexing of the resource when it is a MR, add a dedicated callback function.
