STRUCT MR_PRIV_DEVICE(9)

✨ NAME ✨

struct MR_PRIV_DEVICE — sdev private hostdata. Bestie, this is the struct MR_PRIV_DEVICE(9) page from the Kernel API Manual, and it's lowkey just here to spill the struct tea 💅

🦋 SYNOPSIS 🦋

okay so here's the exact struct, no edits, no cap:

struct MR_PRIV_DEVICE {
    bool is_tm_capable;
    bool tm_busy;
    atomic_t sdev_priv_busy;
    atomic_t r1_ldio_hint;
    u8 interface_type;
    u8 task_abort_tmo;
    u8 target_reset_tmo;
 };

💅 Members 💅

• is_tm_capable — the firmware-managed tm_capable flag, literally firmware's little flag to manage 🎀
• tm_busy — this one means a TM request is in progress, so yeah, it's busy busy 🙈
• sdev_priv_busy — tracks a pending command per sdev, iconic bookkeeping behavior ✨

the synopsis also has r1_ldio_hint, interface_type, task_abort_tmo, and target_reset_tmo — the original page gives those no member blurbs, so I'm not gonna invent lore for them, bestie 💀
