Subject: [PATCH v2 1/8] objtool/klp: Remove redundent strcmp in correlate_symbols
Date: Thu, 19 Feb 2026 14:22:32 -0800 [thread overview]
Message-ID: <20260219222239.3650400-2-song@kernel.org> (raw)
In-Reply-To: <20260219222239.3650400-1-song@kernel.org>
find_global_symbol_by_name() already compares names of the two symbols,
so there is no need to compare them again.
