Subject: [PATCH v4 10/22] objtool: Allow setting --mnop without --mcount
Date: Sat,  8 Aug 2026 16:17:14 -0700	[thread overview]
Message-ID: <339aa792e9eec6de991f72bb3afc6016ddeb3d79.1786230311.git.jpoimboe@kernel.org> (raw)
In-Reply-To: <cover.1786230311.git.jpoimboe@kernel.org>

Instead of returning an error for --mnop without --mcount, just silently
ignore it.  This will help simplify kbuild's handling of objtool args.

Acked-by: Song Liu <song@kernel.org>
