[A General Question] What should I do after getting Reviewed-by from a maintainer?

[Gen Zhang]

Hi Andrew,
I am starting submitting patches these days and got some patches 
"Reviewed-by" from maintainers. After checking the 
submitting-patches.html, I figured out what "Reviewed-by" means. But I
didn't get the guidance on what to do after getting "Reviewed-by".
Am I supposed to send this patch to more maintainers? Or something else?
Thanks
Gen
