Hi,

I have a weird issue on kernel 5.8.0/5.8.1, SIGINT even SIGKILL
doesn't work to kill this process(always state D or D+), literally I
have to terminate my VM because even the kernel can't kill the process
and no issue on 5.7.12-201, however if IOSQE_IO_LINK is not set, it
works

I've attached a file to reproduce it
or here
