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


Yes.  But normally people change their email address instead of their
name.


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


Consistency is less important than being correct...  It's just a weird
thing to say.  Are there other non-community patches with a different
name?  It's fine if that's your legal name and we have made exceptions
for people who aren't able to share their real name because of stalking
or whatever...

I have no non-community patches using any other name, and the accounts in

other systems at my employer also use this name. Thanks.
