set_chunk_bits(9)

💅 set_chunk_bits(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is the page for set_chunk_bits, and honestly? she's short, she's sweet, she's a little helper with one job. let's get into it ✨

---

🌸 NAME 🌸

set_chunk_bits — sets the chunk-related bits in the options field. that's it. that's the whole gig. iconic honestly 🎀

---

✨ SYNOPSIS ✨

void set_chunk_bits (uint16_t *options , int count , int total );

returns nothing (void), takes three things, does not miss. periodt 💅

---

🧚 ARGUMENTS 🧚

• options — a pointer to the options field. she points at the field, you point at her, it's a whole chain of pointing tbh 🫶
• count — the index of the current chunk. like, which chunk are we on right now 🔥
• total — the total number of chunks. the full squad. the whole roster 👑

---

🔥 DESCRIPTION 🔥

so what does she actually do? set_chunk_bits sets the appropriate bits in the options field to indicate whether the current chunk is:

• the first chunk,
• the last chunk,
• or a single chunk 🌈

that's the vibe check she's running, and honestly she ate. three facts about your chunk, encoded in bits, no cap 💜

ngl it's giving "small function, big responsibility" — she's flagging chunk position and everybody downstream is counting on her to be right 🙈

🎀 the cute sign-off 🎀

this page lives in ./drivers/scsi/qla2xxx and it's dated October 2026 — so yeah, she's from the future (or at least the manpage is), and she's still out here setting bits. queen behavior fr fr 👑💖 stay hydrated, read your kernel source, mwah 💋
