Subject: [RFC] perf bench: Adjusting concerns around asynchronous-signal-safety?
Date: Mon, 22 Jul 2024 11:44:25 +0200 [thread overview]
Message-ID: <39a3552f-cbaa-4e29-ac76-95684859787a@web.de> (raw)
Hello,
The functions “gettimeofday” and “timersub” are called within the signal
handler “toggle_done” so far.
https://elixir.bootlin.com/linux/v6.10/source/tools/perf/bench/epoll-ctl.c#L90
Do such implementation details trigger any programming concerns according to
asynchronous-signal-safety?

Regards,
Markus
