bsg_queue_rq(9)

🌸 bsg_queue_rq(9) 🌸

ok so bestie, we're diving into the Kernel API Manual today and this one is literally the generic handler for bsg requests 💅 it's short, it's sweet, it's giving "small function, big job" and honestly? obsessed.

---

✨ NAME ✨

bsg_queue_rq — the generic handler for bsg requests 🫶 like that's her whole thing, that's the vibe.

---

🦋 SYNOPSIS 🦋

blk_status_t bsg_queue_rq (struct blk_mq_hw_ctx *hctx , const struct blk_mq_queue_data *bd );

copy it exactly like that, no cap — return type blk_status_t, two args, go off 👑

---

🎀 ARGUMENTS 🎀

• hctx — the hardware queue 🌈 that's it, that's the whole description, she's a simple icon
• bd — the queue data 💖 again, minimal queen, no notes

---

🔥 DESCRIPTION 🔥

ok so here's the tea, and this part is IMPORTANT so like, pay attention bestie:

On error, the create_bsg_job function should return a -Exyz error value, and that value gets set to ->result. periodt. 💀 that's literally how the error info travels, so like don't be out here returning random nonsense, okay?

also — drivers/subsys should pass this to the queue init function. that's not a suggestion, that's the assignment, fr fr 🙈
