💅 invalidate_inode_pages2(9)

okay so bestie, welcome to the Kernel API Manual — this one's a <purple>section 9</purple> situation and it's literally all about yeeting every single page out of an address_space. no cap. 🧹✨

🌸 NAME 🌸

invalidate_inode_pages2 — remove all pages from an address_space

like, all of them. the whole vibe. gone. 🫶

⭐ SYNOPSIS ⭐

int invalidate_inode_pages2 (struct address_space *mapping );

(yes the spacing in there is exactly what the kernel gods wrote, don't @ me 💀)

🎀 ARGUMENTS 🎀

  • mapping — the address_space. that's the thing we're about to clean out, main character of the whole operation 👑

✨ DESCRIPTION ✨

so here's the tea 🍓: any pages which are found to be mapped into pagetables are unmapped prior to invalidation.

read that again. unmapped first, invalidated after. it's giving "get out of the pagetable before I get you out of the page cache" 💅

🔥 RETURN 🔥

  • -EBUSY — if any pages could not be invalidated. like ok some pages said "no ❤️" and the call had to report it. 😭

🌈 SEE ALSO 🌈

okay that's the whole page, you ate that 🍽️💖
