Re: when/how is the schedule() function actually called?

Hi Billie,

Thanks for getting back to me!
Many sources mentioned the same thing, but where do I find the code that
supports this?

I followed the comment here:
https://github.com/torvalds/linux/blob/c527f5606aa545233a4d2c6d5c636ed82b8633ef/kernel/sched/core.c#L6536C10-L6536C10
to check all the following files:
arch/x86/entry/entry_32.S
arch/x86/entry/entry_64_compat.S
arch/x86/entry/entry_64.S
arch/x86/entry/entry.S

But I don't see any code that is calling the schedule or __schedule
function.
