ldm_frag_add(9)

💅 ldm_frag_add(9) — the kernel API manual bestie

okay so this is ldm_frag_add, a kernel API function, and we're gonna get you fluent in it. no cap. 🫶

---

✨ NAME ✨

ldm_frag_add — adds a VBLK fragment to a list. that's it, that's the whole vibe check.

---

🌸 SYNOPSIS 🌸

bool ldm_frag_add (const u8 *data , int size , struct list_head *frags
);

yes the formatting is a little chaotic, we love her anyway 💖

---

🎀 ARGUMENTS 🎀

• data — the raw fragment, the actual little guy you're adding to the list 🌈
• size — how big that raw fragment is 💫
• frags — the linked list of VBLK fragments, aka where all the pieces hang out together 👑

---

🦋 DESCRIPTION 🦋

so here's the situation, bestie: fragmented VBLKs might not be consecutive in the database. like, they're just not sitting next to each other. rude, honestly. 😭

so because of that, they get placed in a list — that way they can be pieced together later. it's giving puzzle energy, it's giving "we'll deal with this eventually," and honestly? iconic. 🧩✨

---

⭐ RETURN ⭐

ngl the RETURN section here is literally empty. no documented return value, no notes, nothing. we're moving on, periodt. 💀

lowkey reminder: fragmented VBLKs may not be consecutive in the database, which is the whole reason this list situation exists. that's the lore. 🍓
