From e02c9b0d65a7493180db45320f82482c6ba8ea57 Mon Sep 17 00:00:00 2001 From: Lin Feng Date: Tue, 14 May 2019 15:42:34 -0700 Subject: [PATCH] kernel/latencytop.c: rename clear_all_latency_tracing to clear_tsk_latency_tracing The name clear_all_latency_tracing is misleading, in fact which only clear per task's latency_record[], and we do have another function named clear_global_latency_tracing which clear the global latency_record[] buffer.
