ubifs_add_orphan(9)

💅 ubifs_add_orphan — the kernel API manual, but make it make sense

okay so bestie, gather round, because today we're talking about ubifs_add_orphan(9) from the Kernel API Manual and honestly? she's a tiny function with main character energy. 🎀

---

✨ NAME ✨

ubifs_add_orphan — add an orphan. that's it. that's the whole vibe. 🫶

---

✨ SYNOPSIS ✨

int ubifs_add_orphan (struct ubifs_info *c , ino_t inum );

look at her. four arguments of pure function signature realness. no cap. ✨

---

✨ ARGUMENTS ✨

• c — the UBIFS file-system description object 🦋 like, this is the whole filesystem's little info-struct, she's the moment
• inum — the orphan inode number 👑 literally just the number of the inode that's about to be a lonely little orphan

---

✨ DESCRIPTION ✨

okay so here's the tea 🍓: this function adds an orphan. periodt.

it gets called when an inode's link count drops to zero — so like, nobody's pointing at this inode anymore, she's got zero links, she's lowkey orphaned 😭 and this is the function that goes "don't worry bestie, I got you" and adds her to the orphan list.

ngl the whole concept is giving "found family" but for inodes 💜
