Dmitry, Thomas,
To simplify the review I've attached the code with this patch applied below.
Yes, this changes the "semantics" of check_timer_distribution(), perhaps it
should be renamed.
But I do not see a better approach, and in fact I think that

Thomas says:
The signal distribution test has a tendency to hang for a long
time as the signal delivery is not really evenly distributed. In
fact it might never be distributed across all threads ever in
the way it is written.
To me even the

The output goes like this if I make samples/bpf:
...warning: no previous prototype for ‘get_cgroup_id_from_path’...
Make this function static could solve the warning problem since
no one outside of the file calls it.

Introduce a new API to consume items from a ring buffer, limited to a
specified amount, and return to the caller the actual number of items
consumed.

In some cases, instead of always consuming all items from ring buffers
in a greedy way, we may want to consume up to a certain amount of items,
for example when we need to copy items from the BPF ring buffer to a
limited user buffer.
This change allows to set an upper limit to the amount of items
Introduce ring__consume_n() and ring_buffer__consume_n() API to
partially consume items from one (or more) ringbuffer(s).
This can be useful, for example, to consume just a single item or when
we need to copy multiple items to a limited user-space buffer from the
ringbuffer callback.
Practical ex
Bump libbpf.map to v1.5.0 to start a new libbpf version cycle.
