mmc_pre_req(9)

💅 mmc_pre_req(9) 💅

okay so we're in the Kernel API Manual bestie, and today's main character is mmc_pre_req — the little function that gets your MMC host all cute and ready before the actual request shows up. lowkey iconic behaviour tbh 🎀

---

✨ NAME ✨

mmc_pre_req — prepare for a new request 🫶

---

✨ SYNOPSIS ✨

void mmc_pre_req (struct mmc_host *host , struct mmc_request *mrq );

---

✨ ARGUMENTS ✨

• host — the MMC host that's gonna be prepping the command, bestie. this is the one doing the getting-ready montage 💅
• mrq — the MMC request being prepped for. the outfit, if you will 👑

---

✨ DESCRIPTION ✨

so like, mmc_pre_req is called prior to mmc_start_req, fr fr — its whole job is to let the host prepare for the new request before anything actually kicks off. think of it as the vibe check before the party 🌸

and here's the slay part: preparation of a request may be performed while another request is running on the host. so yeah, it's giving multitasking queen energy — no waiting around for the last request to be done before you start getting ready for the next one ✨🔥
