kernfs_get_inode(9)

💅 kernfs_get_inode(9) 💅

okay bestie, welcome to the Kernel API Manual, section 9 — we're doing kernfs_get_inode today and honestly? it's giving "short but iconic" ✨

---

✨ NAME ✨

kernfs_get_inode — get inode for kernfs_node 🎀

---

🦋 SYNOPSIS 🦋

struct inode * kernfs_get_inode (struct super_block *sb , struct
kernfs_node *kn );

---

🌸 ARGUMENTS 🌸

• sb — the super block. yes, that super block. she's the vibe check for the whole thing 🫶
• kn — the kernfs_node we're allocating an inode for. main character energy fr 💅

---

💖 DESCRIPTION 💖

So the way that this works: you use kernfs_get_inode to get the inode for kn. and like — if such inode doesn't exist yet? no worries, bestie, a new inode is allocated and the basics are initialized ✨. the new inode is returned locked 🔒 (not me emphasizing that, it's literally in the page).

Locking: Kernel thread context (may sleep) 😴 — so yes, you can sleep here, it's allowed, we love that for you.

---

🌈 RETURN 🌈

Pointer to the allocated inode on success 🎉, NULL on failure 💀. that's it, that's the whole return.
