STRUCT MEI_CL_CB(9)

💖 NAME 💖

okay so bestie, this is the struct mei_cl_cb(9) page from the Kernel API Manual — and it's literally the file operation callback structure. No cap, that's the whole vibe: struct mei_cl_cb = file operation callback structure. 🫶

✨ SYNOPSIS ✨

the whole struct, served fresh:

struct mei_cl_cb {
    struct list_head list;
    struct mei_cl *cl;
    enum mei_cb_file_ops fop_type;
    struct mei_msg_data buf;
    size_t buf_idx;
    u8 vtag;
    const struct file *fp;
    int status;
    u32 internal:1;
    u32 blocking:1;
    struct mei_ext_hdr *ext_hdr;
};

🧚 Members 🧚

okay, vibe check on every member — no skipping, bestie:

• list — the link that sits in the callback queue.
• cl — the file client who is running this operation.
• fop_type — the file operation type.
• buf — buffer for data associated with the callback.
• buf_idx — last read index.
• vtag — virtual tag.
