okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is struct rtrs_msg_rdma_hdr, and honestly? she's small but she's important.

🌸 NAME 🌸

struct rtrs_msg_rdma_hdr — the header for a read or write request 🫶

Like, that's literally her whole job. She's the little label that says "hey, this thing coming at you is a read or a write." iconic behavior, no notes.

---

✨ SYNOPSIS ✨

struct rtrs_msg_rdma_hdr {
    __le16 type;
};

look at her. one (1) field. she said "I don't need a whole glow-up, I just need to be correct." 💅

🎀 Members 🎀

• type — holds RTRS_MSG_WRITE | RTRS_MSG_READ ⭐ so basically this field is the vibe check for your request: is it a read, or is it a write? that's it, that's the whole personality.

ngl, type is doing a lot of emotional labor here as the only member. protect her at all costs 😭
