From dd1ee9589c12b053ede875f28d6f235187dd8c4f Mon Sep 17 00:00:00 2001 From: Mathieu Desnoyers Date: Wed, 10 Mar 2021 16:23:13 -0500 Subject: [PATCH] counters: add coalesce_hits to ABI This will be required by an upcoming feature in a subsequent release, so plan ahead with a coalesce_hits field. It is currently unused by lttng-modules.
