vdo_compute_index_blocks(9)

🌸 vdo_compute_index_blocks(9) — Kernel API Manual 🌸

okay bestie, welcome to the page for vdo_compute_index_blocks(9), a.k.a. the Kernel API Manual entry you were looking for. This is giving “tiny function, very specific job” energy, and we're gonna cover every detail 💅✨

✨ NAME ✨

vdo_compute_index_blocks — Compute the number of blocks that the indexer will use. That's the whole assignment, no cap 🫶

📜 SYNOPSIS 📜

Here's the exact signature, bestie — don't let the spacing jump-scare you:

int vdo_compute_index_blocks (const struct index_config *config ,
       block_count_t *index_blocks_ptr );

🎀 ARGUMENTS 🎀

• config — the index config from which the blocks are calculated. It's the source info for the math vibe 🔥
• index_blocks_ptr — the number of blocks the index will use. That's the number we're talking about 👑

💖 RETURN 💖

VDO_SUCCESS or an error code. Slay if it's the first one; if not, it's an error code and you deal 💀
