The amount of regression reports that we got in short succession doesn't
make it likely that we can merge a plain degradation.

Let me repeat: this v2 patchset fixes all regressions found so far,
except for major CRIU performance regression

Askar,

As previously mentioned, this isn't just a major performance issue for
CRIU; it completely breaks the current pre-dump implementation.

The other proposed fixes look like workarounds that target specific
projects. Since few projects run tests on linux-next kernels, we should
expect more projects to be affected by these changes.

Thanks,
Andrei
