So I rebased this on rust-next and fixed a few more instances (in
addition to enabling the extra lint), but I realized that rust-next is
still based on v6.14-rc5. I think we're going to have the same problem
here as in the &raw series; either Miguel is going to have to apply
fixups when picking these patches, or we have to split the fixes out
from the lints and land it over several cycles. Thoughts?
