💅 unpin_folios — a Kernel API Manual moment (section 9, bestie)

okay so real talk, this is a page straight outta the Kernel API Manual, section 9, and it's about letting go of folios you grabbed with gup. yes, the letting go part. the emotional climax of every pin. 🫶

✨ NAME ✨

unpin_folios — release an array of gup-pinned folios.

like, an entire array of them. not one, an array. we're doing a whole friend-group goodbye here. 😭

🌸 SYNOPSIS 🌸

void unpin_folios (struct folio **folios , unsigned long nfolios );

that's it. that's the whole signature. she's simple, she's effective, she returns void because she's not gonna sit here and report back to you. 💅

🎀 ARGUMENTS 🎀

  • folios — the array of folios to be marked dirty and released. yes bestie, marked dirty — they're going out with a little chaos on them, as they should. 🔥
  • nfolios — the number of folios in the folios array. like the headcount for the group photo. everybody gets counted, nobody gets left behind. 📋

💖 DESCRIPTION 💖

For each folio in the folios array, release the folio using gup_put_folio.

that's the whole bit, no cap. you hand over the array, she walks it, and every single folio gets released via gup_put_folio. one by one. respectful. orderly. iconic. ✨

Please see the unpin_folio documentation for details. — the singular one! the original! go read that one if you want the full lore, iykyk. 📖
