get_liability(9)

💅 get_liability(9) — from the Kernel API Manual, bestie

Okay so real talk, this one's a tiny little page from the Kernel API Manual, section 9, and it's called get_liability. Short and sweet, but she matters, so let's get into it 🎀

---

✨ SYNOPSIS ✨

long long get_liability (struct ubifs_info *c );

That's it. That's the whole vibe. Returns a long long, takes one pointer, slays 💅

---

🌸 ARGUMENTS 🌸

• c — the UBIFS file-system description object 🦋 like, this is your whole filesystem's little ID card, and we're handing it over.

---

💖 DESCRIPTION 💖

So what does she actually do? get_liability() calculates and returns the current UBIFS liability — which, and I cannot stress this enough, means the amount of bytes UBIFS has "promised" to write to the media 😭

Like... it's the receipts. It's the "yes bestie I said I'd write that" tally. The bytes are promised, not necessarily written yet, and this function hands you the number. Iconic accounting behavior, no cap 👑

Heads up: the word "promised" is in actual quotes in the source material, so take that energy with you — it's a budget/reservation thing, not a "it's already on disk" thing 💀
