Hello All, This is an updated submission of the patch to add an alternative for CONFIG_IKCONFIG. I wanted to bring it up again for consideration, and I also made one small but important update. v1: https://lore.kernel.org/linux-debuggers/20231004165804.659482-1-stephen.s.brennan@xxxxxxxxxx/T/#t Changes since v1: * I added "default y if IKCONFIG!=y". The result is that whenever DEBUG_INFO=y is enabled, and IKCONFIG is not built-in, then DEBUG_INFO_IKCONFIG will get enabled automatically. The whole point of this patch is for kernel debuggers to be able to rely on having kernel configuration information. The IKCONFIG data is quite small compared to kernel debuginfo, and it doesn't change anything at runtime. It's safe to enable this automatically, and it's important so that distributions (who create debuginfo explicitly to allow kernel debugging) will automatically begin creating this info for debuggers. * Randy Dunlap did review this, but I didn't apply that tag with the update, since I understand changing defaults is a major update, and it's a small patch to begin with, so I didn't want to misrepresent the review.
