Hi Masahiro / all, I was rebuilding the kernel today, just adding some debug statements, when I noticed a lot of stuff got built again. I was using ".scmversion" to prevent UTS version changes, so only affected files got indeed rebuilt. After commit f6e09b07cc12 ("kbuild: do not put .scmversion into the source tarball"), seems this file is automatically deleted and I'm not sure how should I proceed to continue with the same behavior. Apologies if this is a silly question, any advice is much appreciated! Also, I've CCed all the emails from [0], so apologies if anybody looped here shouldn't be CCed. Cheers, Guilherme [0] https://lore.kernel.org/lkml/20230122141428.115372-1-masahiroy@xxxxxxxxxx/
