How do I clear all marks from the current buffer mark ring?

Question

Newbie here, but oddly I couldn't find an answer to this by Googling. How do I clear all marks from the current buffer? I did find how to view the mark ring, but not how to clear all marks from current buffer.

Answer 1

M-: (setq mark-ring  ())

That is, just set variable mark-ring to nil.
