From: Stijn Tintel Date: Sun, 20 Feb 2022 01:09:55 +0000 (+0200) Subject: kernel: add DEBUG_INFO_REDUCED config option X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f70b7c33437d2b1237b3b5cc4baafc53bfaa6aa3;p=openwrt%2Fstaging%2Fstintel.git 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.
