Previously, a maintainer suggested that the name should match the email address,

but community patches have consistently used the name "sunliming" since then.

Could you capitalize your name?  It's supposed to be a bit formal like
signing a legal document.

This isn't a RESEND, it's a v2.  A RESEND means we accidentally ignored
your email so now you have to send the exact same email again.
