do_write_orph_node(9)

💜 do_write_orph_node — the manual, but make it make sense

okay bestie so this is a page from the Kernel API Manual (yep, section 9, kernel API, we're literally in the kernel rn) and it's about do_write_orph_node. She writes a node to the orphan head. That's the whole vibe. Let's get into it 🫶

---

✨ NAME ✨

do_write_orph_node — write a node to the orphan head. that's it, that's the job, no cap 💅

---

🌸 SYNOPSIS 🌸

int do_write_orph_node (struct ubifs_info *c , int len , int atomic );

look at her. three args, returns an int. iconic signature, no notes 👑

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. she's the whole file system's little info struct, the main character fr 🌈
• len — length of node. how big the node is. that's the length 💖
• atomic — write atomically. whether we're doing this write atomically or not, it's giving "flag behaviour" ✨

---

🦋 DESCRIPTION 🦋

so here's the tea, bestie 🍓 — this function writes a node to the orphan head, and it pulls that node from the orphan buffer. literally the buffer of orphans. we love a buffer.

if atomic is not zero, then the write is done atomically. that's the whole deal with that arg. zero means not atomic, non-zero means atomic, iykyk 😭

on success, 0 is returned. otherwise a negative error code is returned — so like, if you see a number that's less than zero, that's a no, that's a fail, that's the error telling you what went wrong 💀

ngl this one's short and sweet. no edge cases listed, no warnings listed, no hidden traps. she just writes a node and reports back. periodt 💅

the kernel file is ./fs/ubifs/orphan.c and honestly she has a whole friend group, let's meet them 👑:

okay that's the page!! mwah 💋 this one dropped from ./fs/ubifs, dated October 2026, and she's filed under do_write_orph_node(9) in the Kernel API Manual. go write some orphan nodes responsibly bestie 🧚💜
