I've just send a patch to fix it:
https://lkml.kernel.org/r/20200212140040.126747-1-dima@arista.com

Could you try it?

Also, it seems that the same thing affects futex/rtc/tcp_mmap/tcp_inq tests?

While looking into this, I see there are new auto-generated lkmdtm &&
pidfd tests, is it worth to add them to .gitignore?

Thanks,
          Dmitry
