  • addr β€” the address where the pud is mapped. Like, where is this thing living. πŸ“
  • pud β€” the PUD. That's it, that's the argument. iconic. πŸ‘‘

Okay so the entire mission here is: get the "struct page" that's associated with a PUD. That's the whole thing. ✨

πŸ’– RETURN πŸ’–

  • Returns the "struct page" if this is a "normal" mapping. πŸŽ‰
