Subject: [RFC PATCH v3 02/15] objtool: Flesh out warning related to pv_ops[] calls
Date: Tue, 19 Nov 2024 16:34:49 +0100 [thread overview]
Message-ID: <20241119153502.41361-3-vschneid@redhat.com> (raw)
In-Reply-To: <20241119153502.41361-1-vschneid@redhat.com>
I had to look into objtool itself to understand what this warning was
about; make it more explicit.
