Subject: [PATCH 5.4 051/389] epoll: autoremove wakers even more aggressively

Hi all,
I'm facing an hangup of runc command during startup of containers on Ubuntu 20.04,
just adding this patch to my updated linux kernel 5.4.210.

The runc process exits if I run an strace on it with the strace_runc_hangup.login you can find here

https://github.com/opencontainers/runc/issues/3641

with more details.

Testing it with previous docker-ce/containerio releases, just hangup the runc process and it will remain locked even analyzing it with strace.

Any idea or further test I can do on it?

Thanks,
Michele
