ubi_alloc_aeb(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

ubi_alloc_aeb — bestie, this is the one that allocates an aeb element ✨

So like, quick vibe check: an aeb is a thing you're making from scratch here. That's the whole job. Slay.

🌸 SYNOPSIS 🌸

struct ubi_ainf_peb * ubi_alloc_aeb (struct ubi_attach_info *ai , int pnum , int ec );

That's the whole signature, no cap. Three args in, one pointer out, iconic behavior 💅

🎀 ARGUMENTS 🎀

  • ai — the attaching information 🫶 Like, the whole context you're operating inside of.
  • pnum — the physical eraseblock number ⭐ This is which block we're talking about.
  • ec — the erase counter of the physical eraseblock 🔥 How many times it's been through the erase wringer.

🦋 DESCRIPTION 🦋

Okay so here's the tea ☕ — ubi_alloc_aeb allocates an aeb object, and then it initializes the pnum and ec information for you. Set and done, no extra steps required, main character energy only 👑

And like... what about the other fields? Bestie, they get handled too:

  • vol_id and lnum are set to UBI_UNKNOWN 🙈 (yes, literally that constant, not a vibe, an actual value)
  • the other fields are initialized to zero 🌈 so they're all squeaky clean and blank
⚠️ But WAIT — super important, do not skip this part: the element is not added in any list or RB tree. Like, it exists, it's allocated, it's initialized, but it is not linked up anywhere. It's giving "just moved to town and hasn't been added to the group chat yet" 💀 So if you were expecting it to show up somewhere automatically — it absolutely does not. That's on you, not on this function. Iykyk.
