ubifs_lpt_free(9)

🌸 ubifs_lpt_free — from the Kernel API Manual, bestie edition 🌸

Okay so bestie, we're in the ubifs_lpt_free(9) page today — yes, the (9) means kernel-internals section, we're deep in the kernel basement and it's iconic down here. 🫶

---

✨ NAME ✨

ubifs_lpt_free — free resources owned by the LPT.

Like, it releases the stuff the LPT is holding onto. That's the whole vibe check. 💅

---

🎀 SYNOPSIS 🎀

void ubifs_lpt_free (struct ubifs_info *c , int wr_only );

Returns nothing, takes two things, no drama. She's a void, she doesn't owe you a return value. 😌

---

🦋 ARGUMENTS 🦋

• c — the UBIFS file-system description object. Basically the whole personality of your filesystem in one struct. 🗂️
• wr_only — free only resources used for writing. So if this is set, she's doing a partial cleanup, not the full send. Lowkey selective, highkey valid. ✨

💜 SEE ALSO 💜

So the source situation is: kernel file ./fs/ubifs/lpt_commit.c — that's the mothership. 🚀 And these are all her neighbors, the whole group chat fr fr:

Yeah that's a lot of friends. She's popular. It's giving main character energy. 👑

💀 Real talk though: this is kernel-internal API, so it's not like a cute lil userland command you can just run. It's for people writing in ./fs/ubifs. Iykyk. 🙈

And that's the page! 🌈 This lil beauty lives in ./fs/ubifs, dated October 2026, and goes by ubifs_lpt_free(9) — 🎀 mwah, go free those resources bestie, ily 🎀
