This also has some bugfixes of ftrace which I found including an important deadlock fix. I think uprobe-based events can also support multi-buffer and soft-disabling as I did in this series. --- Masami Hiramatsu (11): [BUGFIX] tracing: Return 0 if event_enable_func succeeded [BUGFIX] ftrace, kprobes: Fix a deadlock on ftrace_regex_lock ftrace: Cleanup regex_lock and ftrace_lock around hash updating [BUGFIX] tracing/kprobes: Fix to increment return event probe hit-count tracing: Indicate enabled soft-mode in enable file [BUGFIX] tracing: Modify soft-mode only if no other referrer [TRIVIAL] tracing/kprobes: Use bool for retprobe checker tracing/kprobes: Increment probe hit-count even if it is used by perf tracing/kprobes: Pass trace_probe directly from dispatcher tracing/kprobes: Support ftrace_event_file base multibuffer tracing/kprobes: Support soft-mode disabling include/linux/ftrace.h | 1 include/linux/ftrace_event.h | 1 kernel/kprobes.c | 1 kernel/trace/ftrace.c | 82 +++++++----- kernel/trace/trace_events.c | 19 ++- kernel/trace/trace_kprobe.c | 289 ++++++++++++++++++++++++++++++++++-------- 6 files changed, 305 insertions(+), 88 deletions(-) -- Masami Hiramatsu IT Management Research Dept. and Linux Technology Center Hitachi, Ltd., Yokohama Research Laboratory
