compat_alloc_user_space() is only used for syscalls AFAIK. The rule is: you
do that, you have to track the kernel. In fact, it is now GPL-only (so, for
example, fglrx needs to be modified as it is forbidden from using

File bugs. Provide as much information as you can, the most useful being
the commits that you want backported, but if you don't know that, at least
full descriptions of the problem, how to reproduce, and what kernel version
you know fixed it would be helpful.

No. It does get patched/bugfixed. That's why we have "point releases", and
that's why it is at 5.0.6 (sixth point release) right now. But you usually
have to prod maintainers to fix something on stable, unless it is a very big
issue or a security issue.
