The rebased series is now available at
https://git.sr.ht/~t-8ch/linux b4/const-sysctl

Nothing much has changed in contrast to v2.
The only functional change so far is the initialization of
ctl_table_header::type in init_header().

I'll wait for Joels and maybe some more reviews before resending it.

For the future I think it would make sense to combine the tree-wide constification
of the structs with the removal of the sentinel values.

This would reduce the impacts of the maintainers.
