The links in the patches show the reviews, even. I assume you're mainly talking about the DMA one; it's right here: https://lore.kernel.org/linux-arm-kernel/20220309175107.195182-1-keescook@chromium.org/ I had thought hch was going to take this patch, but the dma tree didn't have it, so I sent it in. And the usercopy patch was here, with references to the discussion around it too: https://lore.kernel.org/all/20220324230255.1362706-1-keescook@chromium.org/ -- Kees Cook
