nfs_request_..._commit_list(9)

💅 nfs_request_..._commit_list(9) 💅

okay bestie so this is a page from the Kernel API Manual and it's about one tiny little function that does one tiny little thing, and honestly? iconic of it. her whole job is un-committing a request. that's it. that's the vibe. 🎀

---

✨ NAME ✨

nfs_request_remove_commit_list — removes a request from a commit list. she's a remover. a list-leaver. a "you don't have to go home but you can't stay here" girlie. 💅

---

🌸 SYNOPSIS 🌸

void nfs_request_remove_commit_list (struct nfs_page *req , struct
       nfs_commit_info *cinfo );

like, she returns void because she's not here to give you answers, she's here to do the thing. no cap. ✨

---

🦋 ARGUMENTS 🦋

• req — a pointer to a nfs_page. the actual request in question, the main character of this whole situation 🫶
• cinfo — holds the list lock and the accounting info. she's got the receipts, the lock, and the numbers. the responsible friend. 💖

---

🔥 DESCRIPTION 🔥

so the way this works is: she clears the PG_CLEAN bit — yes, literally un-clean-ing it — and then updates cinfo's count of outstanding requests that require a commit. so the accounting stays honest. very demure, very mindful. 🧚

that said, she does not update the MM page stats. not her department. not her problem. don't come for her about the MM page stats. 💀

⚠️ ok this part is serious so listen up bestie: the caller _must_ hold the cinfo->lock and the nfs_page lock. not "should". not "probably". _must_. no lockies = no touchy. fr fr. 🔒

🌈 SEE ALSO 🌈

if you're obsessed with this one (and why wouldn't you be), the kernel file is ./fs/nfs/write.c and the whole friend group is:

• nfs_folio_find_head_request(9)
• nfs_wait_on_request(9)
• nfs_request_add_commit_list_locked(9)
• nfs_request_add_commit_list(9)
• nfs_wb_folio_reclaim(9)
• nfs_wb_folio(9)

go read them. be a well-rounded kernel girlie. 👑

and that's the whole page, bestie, no crumbs left behind. this little gem lives in ./fs/nfs and it's dated October 2026, served up fresh from the Kernel API Manual. mwah, go hold those locks 💜💅✨
