It makes the build slightly slower (from [1], 3.858 -> 3.991 (+3%) on my crippled machine for the vmlinux BTF phase -- the modules also get similar treatment, I'm not sure how big the total time exactly is -- for large kernels with tons of modules it definitely adds up but for small kernels it's probably "short enough") [1] https://lkml.kernel.org/r/20240626032253.3406460-1-asmadeus@xxxxxxxxxxxxx I don't particularly mind either way, so this is mostly out of curiosity: do we have any other setting that would be closer better than this KBUILD_BUILD_TIMESTAMP to say "make this reproducible", or is the kernel build supposed to be reproducible except for the date by default?
