From 3138df6f0cd04a75f8efa5b5270ba56d00a84ae6 Mon Sep 17 00:00:00 2001 From: Crystal Wood Date: Wed, 12 Nov 2025 09:25:28 -0600 Subject: [PATCH] rtla/timerlat: Exit top main loop on any non-zero wait_retval Comparing to exactly 1 will fail if more than one ring buffer event was seen since the last call to timerlat_bpf_wait(), which can happen in some race scenarios.
