That doesn't make sense, I want to see patches that are being proposed
for the stable kernels _before_ they get into the maintainers and
Linus's tree, as then, it is almost always too late.

I will point out the zram patch this weekend as an example of that,
where if the original had gone in, it would be a while before the
"fixup" would have then gone in, and the abi deprecation would probably
have missed 4.11 entirely.

Don't you want to catch things earlier rather than later?
