💅 pcpu_chunk_populated(9) — Kernel API Manual 💅

okay so bestie, we're in the Kernel API Manual today and this function is genuinely so important, ngl. it's called pcpu_chunk_populated and it's the post-population bookkeeping queen 👑

✨ NAME ✨

pcpu_chunk_populated — post-population bookkeeping. that's it, that's the whole vibe. it does the paperwork after the pages move in 💖

🎀 SYNOPSIS 🎀

void pcpu_chunk_populated (struct pcpu_chunk *chunk , int page_start ,
       int page_end );

literally that's the whole call. slay.

🦋 ARGUMENTS 🦋

  • chunk — the pcpu_chunk that got populated. the main character of this whole operation 💅
  • page_start — the start page. where the party begins ✨
  • page_end — the end page. where the party stops 🫶

🌸 DESCRIPTION 🌸

so here's the tea: the pages in [page_start,page_end) have been populated into chunk. note the half-open interval bestie, page_end is not included, that's just how it is 🎀

your job here is to update the bookkeeping information accordingly. the way that this function keeps receipts is honestly iconic. 👑

and this part is NOT optional: must be called after each successful population. like, every single one. no skipping, no "I'll do it later", no cap. it's required, fr fr 🔥

💜 SEE ALSO 💜

okay this is the friend group, the whole squad, and they're all in the kernel file ./mm/percpu.c — go say hi:

ngl, the pcpu_chunk_depopulated(9) girlies and the pcpu_chunk_populated(9) girlies are lowkey in a rivalry and I respect it 😭

and that's the page bestie!! this one lives under ./mm and the version stamp says October 2026 — so go forth, populate your chunks, and always do your bookkeeping 💖✨🎀 🦋 🌈 ⭐ 👑 💜
