ldm_ldmdb_add(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

ldm_ldmdb_add — okay so this is the function that adds a raw VBLK entry to the ldmdb database ✨ (yes bestie, this is from the ldm_ldmdb_add(9) page in the Kernel API Manual, we're doing kernel internals today and honestly? iconic.)

🌸 SYNOPSIS 🌸

bool ldm_ldmdb_add (u8 *data , int len , struct ldmdb *ldb );

She takes three things and gives you back a bool, no cap 🫶

🎀 ARGUMENTS 🎀

  • data — the Raw VBLK you want to add to the database. Like the actual raw bytes, hand them over 💅
  • len — Size of the raw VBLK. Gotta tell her how big the thing is or she's lost fr.
  • ldb — Cache of the database structures. This is the little home where everything gets filed away 🗂️

🦋 DESCRIPTION 🦋

So the VBLKs get sorted into categories — that's the whole vibe. And the partitions? They also get sorted, by offset. Neat and tidy, main character energy 🌈

N.B. — and this is the important bit, don't skip it: this function does not check the validity of the VBLKs. Like at all. Zero vibe check, zero validation, it just trusts you. So maybe don't hand it garbage 🙈💀

⭐ RETURN ⭐

Literally nothing here in the original — the section exists and it's empty, so that's the whole tea. No return-value prose to report, bestie 🍓

👑 SEE ALSO 👑

Kernel file ./block/partitions/ldm.c, plus the whole squad of related functions (yes, all of them, we're listing every single one 💜):

That's the whole page, bestie — go forth and add those raw VBLKs responsibly 🧚💖

Mwah 💋 — this masterpiece lives in ./block/partitions, dated October 2026, and it's the ldm_ldmdb_add(9) page. Slay, periodt. ✨
