Yep, the mixed cases are bit tough to automatically enforce. So the transitional phase will always be troublesome, and trying to make that shorter makes some sense to me. Traditionally we've avoided mass changes just for the changes, but we have to assess the value of doing it against what we get. That is getting automatic enforcement, once we've converted over. We're not that far off the mark with u(32|16|8) vs uint(32|16|8)_t: i915$ git grep -E "uint(32|16|8)_t" | wc -l 852 i915$ git grep -E "u(32|16|8)" | wc -l 3857 I don't consider that undoable. BIT() is in the minority at the moment, so it might benefit even more as people often cargo-cult the programming style from other places in the code. I think it might be worthy doing these two changes to get the automatic enforemend and avoid the codebase staying in limbo. Machine overlords are way better at enforcing any code checks than us humans.
