And the 35 places is only .c files. This is a very nice reduction of bloat! I hope this has a measureable effect on building times.
I was working on something similar, but that approach only added missing includes, and did not kill all the unnessesary includes - which I think is the biggest win here. All patches are: Reviewed-by: Sam Ravnborg <s...@ravnborg.org> For a few of them the r-b is conditional, see the specific comments posted. I did a build check here with the archs and config I verifies with. This covers "alpha arm arm64 sparc64 i386 x86 powerpc s390 riscv sh" and everything was fine. I have a few specific configs to pull in drivers that need a bit extra to be built. So I consider build coverage OK for applying, but it would be nice to wait a few days for the bots to verify too. My own work on slimming drm_atomic_helper.h and drm_print.h will be rebased on top of your work before I continue it. I need to look into removing unused includes too.
