I plan to work on the weekend to plugging his latest series on top of these patches so that we can get it merged in the next merge window. Any comment/test is more than welcome, - Arnaldo Arnaldo Carvalho de Melo (2): perf trace augmented_syscalls.bpf: Move the renameat augmenter to renameat2, temporarily perf trace: Use a common encoding for augmented arguments, with size + error + payload tools/perf/trace/beauty/perf_event_open.c | 2 +- tools/perf/trace/beauty/sockaddr.c | 2 +- tools/perf/trace/beauty/timespec.c | 2 +- .../bpf_skel/augmented_raw_syscalls.bpf.c | 108 +++++++++++------- 4 files changed, 68 insertions(+), 46 deletions(-) -- 2.46.0
