nfs_inode_fi..._attr_update(9)

💅 nfs_inode_fi..._attr_update(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: it's a kernel manual page, the name got abbreviated to nfs_inode_fi..._attr_update(9) because apparently even the title needed a vibe check, and it lives in the Kernel API Manual. yes bestie, they really truncated their own function name. iconic behavior honestly. let's get into it ✨

---

🌸 NAME 🌸

nfs_inode_finish_partial_attr_update — the little cleanup crew that completes a previous inode update. it's giving finishing-what-someone-else-started energy 💅

---

✨ SYNOPSIS ✨

int nfs_inode_finish_partial_attr_update (const struct nfs_fattr *fattr
, const struct inode *inode );

she takes two const pointers and returns an int. no cap, that's the whole signature 🫶

---

🦋 ARGUMENTS 🦋

• fattr — the attributes, bestie. this is your const struct nfs_fattr *, and it's the thing that has to match up for the magic to happen 💖
• inode — a pointer to the inode. const struct inode *, literally just pointing at the inode in question 🌸

---

💀 DESCRIPTION 💀

okay so here's the tea ☕ — this function returns '1' if the last attribute update left the inode's cached attributes sitting in a partially unrevalidated state, and fattr matches the change attribute of that partial update. both conditions, together, or it's a no 💅

otherwise? it returns '0'. that's it. that's the whole plot.

so basically it's a yes/no vibe check on whether you're looking at the leftover half-finished state from a previous update, and whether the attributes you're holding actually line up with it. 1 = yeah that's the partial update, 0 = nope, not it 🙈
