Merge tag 'trace-tools-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull tracing tooling updates from Steven Rostedt:

- Allow RTLA to collect data via BPF

The current implementation of rtla uses libtracefs and libtraceevent
to pull sample events generated by the timerlat tracer from the trace
buffer. rtla then processes the sample by updating the histogram and
summary (current, maximum, minimum, and sum values) as well as checks
if tracing has been stopped due to threshold overflow.

In use cases where a large number of samples is being generated, that
is, with measurements running on many CPUs and with a low interval,
this sample processing design causes a significant CPU load on the
rtla side. Furthermore, with >100 CPUs and 100us interval, rtla was
reported as not being able to keep up with the samples and dropping
most of them, leading to it being unusable.

Change the way the timerlat trace processes samples by attaching a
BPF program to the trace event using the BPF skeleton feature of
bpftool. Unlike the current implementation, the BPF implementation
does not check whether tracing is stopped (in BPF mode, tracing is
always off to improve performance), but waits for a write to a BPF
ringbuffer instead. This allows rtla to exit immediately when a
threshold is violated, without waiting for the next iteration of the
while loop.

If the requirements for the BPF implementation are not met, either at
build time or at run time, the current implementation is used as
fallback. Which implementation is being used can be seen when running
rtla timerlat with "-D" option. rtla can be forced to run in non-BPF
mode by setting the RTLA_NO_BPF option to 1, for debugging purposes.

- Fix LD_FLAGS from being dropped in build

- Refactor code to remove duplication of save_trace_to_file

- Always set options and do not rely on default settings

Do not rely on the default kernel settings of the tracers when
starting. They could have been changed by the user which gives
inconsistent results. Always set the options that rtla expects.

- Add creation of ctags and TAGS for traversing code
