From bd49784fd1e8f42c7600fbfa206361324857f373 Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Tue, 18 Aug 2015 16:26:16 -0400 Subject: dm stats: report precise_timestamps and histogram in @stats_list output If the user selected the precise_timestamps or histogram options, report it in the @stats_list message output. If the user didn't select these options, no extra tokens are reported, thus it is backward compatible with old software that doesn't know about precise timestamps and histogram.
