Default Bug#639919: linux-2.6: please enable DEBUG_STRICT_USER_COPY_CHECKS

Package: linux-2.6
Version: 3.0.0-3
Severity: wishlist

Hey,

this was already asked as part of #605090 but I had the impression that
opening a bug was needed since people were aware, but I was wrong.

So here's a wishlist bug. Could DEBUG_STRICT_USER_COPY_CHECKS be
enabled?

It's used to enforce checks for the various copy_* to prevent overflows
etc. This is done at compile time, and, afaict, it worked fine (on
i386/amd64 Debian kernels) since 2.6.37.

Regards,
