Subject: [PATCH] kbuild: disable DEBUG_INFO_SPLIT when BTF is on
Date: Tue, 31 Mar 2020 19:47:20 +0300 [thread overview]
Message-ID: <20200331164719.15930-1-slava@bacher09.org> (raw)
Currently turning on DEBUG_INFO_SPLIT when DEBUG_INFO_BTF is also
enabled will produce invalid btf file, since gen_btf function in
link-vmlinux.sh script doesn't handle *.dwo files.
