ENUM IB_T10_DIF_BG_TYPE(9)

💖 enum ib_t10_dif_bg_type(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one is short and sweet and it's literally just about which flavour of checksum math we're doing for T10-DIF block guards. no cap, tiny page, big vibes 🎀

---

🌸 NAME 🌸

enum ib_t10_dif_bg_type — the Signature T10-DIF block-guard types 🛡️ like, the what kind of math is guarding this block enum, iykyk

---

✨ SYNOPSIS ✨

enum ib_t10_dif_bg_type {
    IB_T10DIF_CRC ,
    IB_T10DIF_CSUM

};

she's small, she's iconic, she has a slightly unhinged trailing comma situation and we respect it 💅

---

🦋 CONSTANTS 🦋

• IB_T10DIF_CRC — this one corresponds to the T10-PI mandated CRC checksum rules 🔥 like, the spec says CRC, so we do CRC, periodt. it's giving "rules are rules" energy 👑
• IB_T10DIF_CSUM — and this one corresponds to IP checksum rules 🌈 different math, different vibe, still valid, still slaying 🫶

fr fr bestie, these are just two labels in an enum — you're not calling functions here, you're picking which checksum ruleset you mean. don't overthink her 💀

👀 SEE ALSO 👀

go read the source, she's right there in the kernel file ./include/rdma/signature.h:

• enum ib_signature_type(9)
• struct ib_t10_dif_domain(9)
• struct ib_sig_domain(9)
• struct ib_sig_attrs(9)

all the signature-adjacent besties, all in one header, we love a cohesive friend group 💜

and that's the whole page, babe 🧚 this lil icon came to you from ./include/rdma, dated October 2026, and it lives at enum ib_t10_dif_bg_type(9) 🍓 mwah, go checksum something 💋⭐
