As a reminder, I added .b4-config to the top-level, so that using the kernel's b4 tool inside a GCC source tree will automatically use inbox.sourceware.org and will submit mail to gcc-patc...@gcc.gnu.org
See https://b4.docs.kernel.org/en/latest/ for docs on how to use b4 to work with patches in the inbox.sourceware.org archives. I'll add this info to the wiki. (And the .editorconfig info, and git commit signing info, and sourcehut info ...)
