Hi, Stephan
How are you. My name is Rong Tao, from China.
I just saw your article linux-kernel-interrupts. I need your help, if you can lend me your hand.
when i test real-time patch of kernel 3.10.0(CentOS 7.4,7.8), and use epoll, eventfd syscalls for four threads, then Rescheduling interrupts is Explosion, as follows: (about add 10w per second)

 RES:    3148644    3873847     202563     274326   Rescheduling interrupts

kernel and rt-patch version

# uname -r
3.10.0-1127.rt56.1093.el7.x86_64

but if i use 3.10.0-1062.el7.x86_64 is totally OK( Rescheduling interrupts: add 10/s - 100/s),

I don't know how that happen.
best wishes for you.

Rong Tao.
