I wrote a BPF tool: github.com/mfleming/perfo…
I always wished time(1) displayed useful statistics like off-cpu time and whether the program was blocked on i/o (or sleeping in userspace). schedtime gives you that info by inspecting callstacks to work out why your app blocked.

I certainly didn't expect to find such accurate description of the Linux kernel development process at the end of a fantasy book. pic.twitter.com/s5h9XMd3LW

O ulici vedle to tak hrozné nebývá. Podle mě za to můžou ty tramvajové koleje.

Souhlas ale já mám asi smůlu, stejné problémy jsem měl i s kupony na platební kartě. Za ty nervy a nepříjemné průvodčí mi to nestojí.

Ve vlacích ČD? I měsíc od spuštění se našly průvodčí a terminály, pro které byla aplikace neznámý identifikátor a karta prošla, přestože na ní kupony dávno nebyly. Nový kupon jsem radši koupil zase na kartu, aby se nestalo že nebude vidět nikde.
