BTW for future reference your subject should contain both PATCH and RFC https://www.kernel.org/doc/html/latest/process/submitting-patches.html "The summary phrase may be prefixed by tags enclosed in square brackets: “Subject: [PATCH <tag>...] <summary phrase>”. The tags are not considered part of the summary phrase, but describe how the patch should be treated. Common tags might include a version descriptor if the multiple versions of the patch have been sent out in response to comments (i.e., “v1, v2, v3”), or “RFC” to indicate a request for comments."
