Subject: [PATCH v3 9/9] objtool/klp: Fix line numbers in Module.symvers parse errors
Date: Fri, 7 Aug 2026 14:37:54 -0700 [thread overview]
Message-ID: <133e16bb0c7cb916f10bbfb017eba525449ad1d6.1786138493.git.jpoimboe@kernel.org> (raw)
In-Reply-To: <cover.1786138493.git.jpoimboe@kernel.org>
read_exports() reports the offending line number when it fails to parse
Module.symvers. The counter is initialized to 1 but never incremented,
so every error blames line 1 regardless of where the bad line is.
