okay so bestie, welcome to the Kernel API Manual — this is a kernel function page, and honestly it's a short one, so let's just get into it 🎀

✨ NAME ✨

nilfs_bmap_read — read a bmap from an inode 🦋

---

✨ SYNOPSIS ✨

int nilfs_bmap_read (struct nilfs_bmap *bmap , struct nilfs_inode
*raw_inode );

---

✨ ARGUMENTS ✨

• bmap — the bmap, bestie. that's literally it, that's the argument 💅
• raw_inode — the on-disk inode 🌸

---

✨ DESCRIPTION ✨

so nilfs_bmap_read initializes the bmap bmap. that's the whole vibe check. it takes your bmap and gets it set up, no cap ✨

---

✨ RETURN ✨

0 on success 🎉 — or one of these negative error codes when it's not giving:

• -EIO — I/O error (corrupted bmap). 😭 yeah the bmap is corrupted, that's rough, that's a whole situation
• -ENOMEM — insufficient memory available. 💀 not enough memory, tragic, we've all been there
