Which means I believe we have a semantically valid change in behavior that is causing a regression.

I haven't made a survey of all of the functions yet but fucntions return -ENORESTARTNOHAND will never return -EINTR and are immune from this problem.

AKA pselect is fine. While epoll_pwait can be affected.

Has anyone contacted Omar Kilani to see if that is his issue? https://lore.kernel.org/lkml/CA+8F9hicnF=kvjXPZFQy=Pa2HJUS3JS+G9VswFHNQQynPM...

So far the only regression report I am seeing is from Eric Wong. AKA https://lore.kernel.org/lkml/20190501021405.hfvd7ps623liu25i@dcvr/ Are there any others? How did we get to be talking about more than just epoll_pwait?
