ubifs_read_sb_node(9)

👑 ubifs_read_sb_node(9) 💫

Okay bestie, welcome to the Kernel API Manual — yes, the actual kernel manual, and yes, this page is about one very specific little function that lives in the UBIFS filesystem magic. Sit down, hydrate, let's get into it 🫶

---

✨ NAME ✨

ubifs_read_sb_node — read superblock node. That's it, that's the whole vibe. One job. Iconic behavior honestly 💅

---

🌸 SYNOPSIS 🌸

struct ubifs_sb_node * ubifs_read_sb_node (struct ubifs_info *c );

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. Your little info-struct bestie that tells this function everything it needs to know about the filesystem it's working with 🦋

---

🧚 DESCRIPTION 🧚

So here's the tea: this function returns a pointer to the superblock node or a negative error code. Either you get the goods or you get a sad little negative number, no in-between 😭

⚠️ Heads up, this part matters: the user of this function is responsible for kfree'ing the returned superblock buffer. Not the function. Not the kernel. You. So like... don't just walk away from it, bestie, that's a memory leak and it's giving chaos 💀

---

🔥 SEE ALSO 🔥

• Kernel file ./fs/ubifs/sb.c — the source of truth, the main character file itself 👑
• create_default_filesystem(9)
• validate_sb(9)
• ubifs_write_sb_node(9)
• ubifs_read_superblock(9)
• fixup_leb(9)
• fixup_free_space(9)
• ubifs_fixup_free_space(9)

All of these are siblings in the same ./fs/ubifs household, and honestly they all ate 🍓
