STRUCT UFS_QUERY_RES(9)

💅 struct ufs_query_res(9)

okay so real talk, this is a page straight out of the Kernel API Manual (yep, that's the manual name, and yes bestie, that's the whole flex) and it's giving "tiny struct, huge friend group" energy. Let's get into it 🫶

---

✨ NAME ✨

struct ufs_query_res — the UPIU QUERY response, aka the lil container that holds what came back when you asked a UFS device a question 🎀

---

🌸 SYNOPSIS 🌸

Here's the whole thing, and honestly? She's short and she knows it:

struct ufs_query_res {
    struct utp_upiu_query upiu_res;
 };

That's it. That's the struct. one (1) member, no cap 💀

---

🦋 Members 🦋

• upiu_res — the query response data itself, a struct utp_upiu_query. This is the actual payload, the main character of this whole structure, the reason she exists 🔥

like, that's a whole group chat right there and she's on every single one of those pages. social butterfly behavior fr fr 🦋✨

go read them if you wanna actually understand the UFS host controller driver, because this page alone is basically just a name tag at the party 🎀

and that's the whole page bestie!! short, sweet, iconique. this gem comes to you from ./include/ufs, dated October 2026 — mwah, sending u a kiss, go write some kernel code 💜💅
