Changes in v3: - Change the regex pattern in struct augmentation (Ian) Changes in v2: - Add an extra newline after error messages - Rename the title of patch 3 to 'Stop tracing hrtimer_setup...' - Take the debug diff for explanation out of patch 5 to make it apply normally - Add base-commit in this cover letter Howard Chu (6): perf test trace: Use shell's -f flag to check if vmlinux exists perf test trace: Remove set -e and print trace test's error messages perf test trace: Stop tracing hrtimer_setup event in trace enum test perf test trace: Remove set -e for BTF general tests perf test trace BTF: Use --sort-events in BTF general tests perf test trace BTF: Change the regex pattern in the struct test tools/perf/tests/shell/trace_btf_enum.sh | 17 +++++++++-------- tools/perf/tests/shell/trace_btf_general.sh | 19 +++++++++---------- 2 files changed, 18 insertions(+), 18 deletions(-) base-commit: 628e124404b3db5e10e17228e680a2999018ab33 -- 2.45.2
