From 44bcad24b6f330aae73994e881e25df0fd7a490d Mon Sep 17 00:00:00 2001 From: Stijn Tintel Date: Sun, 20 Feb 2022 03:09:55 +0200 Subject: [PATCH] kernel: add DEBUG_INFO_REDUCED config option Add DEBUG_INFO_REDUCED as a kernel config option and remove it from the kernel configs. This is in preparation of the upcoming option to enable BTF typeinfo, which is incompatible with DEBUG_INFO_REDUCED.
