workingset_age_nonresident(9)

💅 NAME 💅

workingset_age_nonresident — bestie, this one ages your non-resident entries right alongside the LRU ages ✨

🌸 SYNOPSIS 🌸

void workingset_age_nonresident(struct lruvec *lruvec, unsigned long nr_pages);

🎀 ARGUMENTS 🎀

• lruvec — the lruvec that just got aged 👑 like, the actual victim of the aging, okay?
• nr_pages — how many pages we're counting here 💖

🦋 DESCRIPTION 🦋

okay so picture this: your in-memory pages are out here getting aged, right? and the non-resident pages are just sitting there like 👁️👄👁️ — no. not on our watch. non-resident pages gotta be aged too, because otherwise the refault distances later on are literally not comparable to the in-memory dimensions, and that's a vibe check nobody wants to fail 😭

so this function is the whole point: it lets reclaim and LRU operations drive the non-resident aging along in parallel 🫶 two things, one motion, main character energy fr fr.
