I completed some thorough testing on these patches now, and have injected
trace_printk()s (in a way to allow it to safely recurse) to force various
data races and then examined the trace to make sure that everything it did
was exactly what I expect it to do, or in cases where it did something

Up until now, if an event is interrupted while it is recorded by an
interrupt, and that interrupt records events, the time of those events will
all be the same. This is because events only record the delta of the time

It would be great if you can show some results from
bpf_iter_task_stack.c dump.

Attention Beneficiary!!!
We have actually been authorized by the newly appointed United
Nation’s Secretary-General, and the governing body of the UNITED
NATION’S Monetary Unit, to investigate the unnecessary delay on your
compensation payment, recommended and approved in your favor. During
the cou
Introduce helper bpf_get_task_stack(), which dumps stack trace of given
task. This is different to bpf_get_stack(), which gets stack track of
current task. One potential use case of bpf_get_task_stack() is to call
it from bpf_iter__task and dump all /proc//stack to a seq_file.
bpf_get_task_stack()
This makes it easy to dump stack trace in text.

This set introduces a new helper bpf_get_task_stack(). The primary use case
is to dump all /proc/*/stack to seq_file via bpf_iter__task.
A few different approaches have been explored and compared:
1. A simple wrapper around stack_trace_save_tsk(), as v1 [1].
This approach introduces new s
