Ah, it's an inline function in newer kernel trees as well so that the build warning isn't there anymore. As this change feels odd for 6.6 and older kernels, AND it's causing build warnings, I'm just going to drop it and if the riscv maintainers really want it applied to these trees, will take a working backport from them. thanks, greg k-h
