From aba11831794356ff58da69de46a125e6335eb9ca Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 19 Dec 2018 10:59:49 -0500 Subject: [PATCH] xprtrdma: Clean up of xprtrdma chunk trace points The chunk-related trace points capture nearly the same information as the MR-related trace points. Also, rename them so globbing can be used to enable or disable these trace points more easily.
