STRUCT IB_T10_DIF_DOMAIN(9)

💅 struct ib_t10_dif_domain(9) — like, the T10-DIF domain struct bestie

okay so this is a page straight out of the Kernel API Manual (yes, the Kernel API Manual, we're fancy now ✨) and it's all about struct ib_t10_dif_domain — the little bundle of parameters that's specific to a T10-DIF domain. ngl it's a glow-up for your protection-information vibes 🎀

🌸 NAME 🌸

struct ib_t10_dif_domain — the parameters that are, like, specific to the T10-DIF domain 💖

---

✨ SYNOPSIS ✨

struct ib_t10_dif_domain {
    enum ib_t10_dif_bg_type bg_type;
    u16 pi_interval;
    u16 bg;
    u16 app_tag;
    u32 ref_tag;
    bool ref_remap;
    bool app_escape;
    bool ref_escape;
    u16 apptag_check_mask;
 };

like, that's the whole squad right there 👑 copy it exactly, no cap 🙈

okay bestie, field-by-field field trip, let's go 🫶

• bg_type — the T10-DIF block guard type. it's giving CRC|CSUM energy 💅
• pi_interval — the protection information interval ⭐
• bg — the seed of the guard computation 🌱 (yes, a seed, iconic)
• app_tag — the application tag of the guard block 🎀
• ref_tag — the initial guard block reference tag 📌
• ref_remap — tells you whethear the reftag increments each block 👀 (that's the original's spelling, i'm just the messenger, mwah 💋)
• app_escape — says to skip the block check if apptag=0xffff 🚪💨
• ref_escape — says to skip the block check if reftag=0xffffffff 🚪💨
• apptag_check_mask — the check bitmask of the application tag 🔍

fr fr bestie, don't forget: everything above is exactly what the page says — i'm just here to make it cute, not to change a single byte of the facts 💀✨
