Message-Id: <20231004004959.work.258-kees@kernel.org> Date: Tue, 3 Oct 2023 17:50:03 -0700 From: Kees Cook <keescook@...omium.org> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: Kees Cook <keescook@...omium.org>, Thomas Gleixner <tglx@...utronix.de>, workflows@...r.kernel.org, linux-doc@...r.kernel.org, Jonathan Corbet <corbet@....net>, linux-kernel@...r.kernel.org, linux-hardening@...r.kernel.org Subject: [PATCH] Documentation: embargoed-hardware-issues.rst: Clarify prenotifaction There has been a repeated misunderstanding about what the hardware embargo list is for. Clarify the language in the process so that it is clear that only fixes are coordinated. There is explicitly no prenotification process. The list members are also expected to keep total radio silence during embargoes.
