nfs_pageio_do_add_request(9)

📦 version 7.3.1, in nixpkgs unstable

💅 nfs_pageio_do_add_request(9) — the kernel API manual, bestie edition 🎀

okay so this is a section 9 kernel API manual page, and the star of the show is nfs_pageio_do_add_request — yes that's a whole mouthful, we're saying it with our chest 🫶

✨ NAME ✨

nfs_pageio_do_add_request — the little function that attempts to coalesce a request into a page list. attempt being the operative word, bestie, no promises 👀

🌸 SYNOPSIS 🌸

unsigned int nfs_pageio_do_add_request (struct nfs_pageio_descriptor
*desc , struct nfs_page *req );

like yes it's two lines, it's giving "the signature didn't fit", we don't judge 💅

🦋 ARGUMENTS 🦋

  • desc — the destination io descriptor. that's the page list we're trying to slide req into 🎯
  • req — the request. the whole point. the main character, honestly 👑

💖 DESCRIPTION 💖

so here's the vibe check: if the request req was successfully coalesced into the existing list of pages desc, then it returns the size of req. that's it. that's the whole function. short, sweet, iconic ✨

notice the if, bestie — successful coalescing is the condition, and the return value is literally the size of req 🌸

ngl this is a "does one thing and does it well" situation and we respect it fr fr 🫶

🌈 SEE ALSO 🌈

kernel file ./fs/nfs/pagelist.c — that's where the magic lives, go look 👀

and then the whole squad, in the order they showed up to the group chat:

like that's a lot of friends and every single one of them is linked, we love a well-connected queen 🧚💜

and that's the whole page, bestie!! this one came from ./fs/nfs, stamped October 2026, and it's filed under nfs_pageio_do_add_request(9) — slay, periodt, see u in the next man page 😭💖✨
