Agree, when I pick up this tags, I am a little not sure whether this is
correct.

Hmm... this one is not that exact. This function is introduced in commit
ca79b0c211af and no one use it on its birth.

Maybe we need to change it to:

totalram_pages_set() is introduced in commit ca79b0c211af ("mm: convert
totalram_pages and totalhigh_pages variables to atomic"), but no one
use it.

Thanks for your comments:-)
