nfs_request_add_commit_list(9)

💅 nfs_request_add_commit_list(9) ✨

okay bestie, so this is a page from the Kernel API Manual — yes, the kernel manual, we're doing big-brain stuff today 🧠💖 — and it's all about nfs_request_add_commit_list. grab a lil snack and let's get into it 🍓

---

🌸 NAME 🌸

nfs_request_add_commit_list — literally just add a request to a commit list, that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

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

no cap, it returns void — nothing comes back, so don't go looking for a return value, she doesn't have one 💀

---

🦋 ARGUMENTS 🦋

• req — pointer to a struct nfs_page 👑 this is the request in question
• cinfo — holds the list lock and the accounting info 🧾 like, it's the keeper of the numbers

---

💜 DESCRIPTION 💜

okay so here's what goes down:

• it sets the PG_CLEAN bit ✅
• it updates the cinfo count of how many outstanding requests are requiring a commit 🔥
• and it updates the MM page stats too 📊 (yep, all three, she's an overachiever, periodt)

⚠️ important rules, bestie, do NOT skip these: the caller must _not_ hold cinfo->lock, but the caller must be holding the nfs_page lock. not one, not the other way — exactly that way. flip it and you're gonna have a bad time 😭💀
