[CRIU] crtools error: "can't splice to pipe"

[Andrey Wagin]

Hi J F,

It's good news for us and bad news for you.

If you see such messages, it's always something wrong in the kernel.
You can try to update kernel. If it doesn't help, you will need to
report this bug to your distribution's bugzilla.

Thank you for the report, it helped us to find a few bugs in CRIU. And
we are sorry that we can't help you.
