nilfs_iget_for_shadow(9)

🎀 NAME 🎀

okay bestie, welcome to nilfs_iget_for_shadow(9) — straight out of the Kernel API Manual ✨

nilfs_iget_for_shadow — obtain inode for shadow mapping 💅

---

✨ SYNOPSIS ✨

struct inode * nilfs_iget_for_shadow (struct inode *inode );

---

🌸 ARGUMENTS 🌸

• inode — the inode object that uses shadow mapping, periodt 🫶

---

🦋 DESCRIPTION 🦋

So nilfs_iget_for_shadow allocates a pair of inodes that holds page caches for shadow mapping. No cap, it's giving package deal 💖

The page cache for data pages is set up in one inode, and the page cache for b-tree node pages is set up in the other inode — and that other inode is attached to the former inode. Obsessed with the attachment lore, ngl 🔥

---

🌈 RETURN 🌈

On success you get a pointer to the inode for data pages 🎀

Or, if memory is insufficient, you get -ENOMEM 😭
