From e641f696ebe4514efac00d1f4a485a06c8e94eea Mon Sep 17 00:00:00 2001 From: Tom Huynh Date: Tue, 2 Dec 2014 11:37:22 -0600 Subject: [PATCH] perf hists browser: Change print format from %lu to %PRIu64 The nr_events variable in tools/perf/ui/browsers/hists.c is of type u64, so the print format (%lu) causes 'perf report' to show 0 event count when running with 32-bit userspace without redirection. This patch fixes that problem by printing nr_events as PRIu64.
