STRUCT LIVEUPDATE_FILE_OP_ARGS(9)

💅 NAME 💅

struct liveupdate_file_op_args — bestie, this is the args bundle for the file operation callbacks. it's giving "one struct to hold them all" ✨

---

🎀 SYNOPSIS 🎀

okay so here's the whole thing, no cap, exactly as it is:

struct liveupdate_file_op_args {
    struct liveupdate_file_handler *handler;
    int retrieve_status;
    struct file *file;
    u64 serialized_data;
    void *private_data;
 };

---

🌸 Members 🌸

• handler — the file handler that's getting called rn. like, the one on the aux cord 🎧
• retrieve_status — the retrieve status for the 'can_finish / finish' operation. so listen: a value of 0 means the retrieve has not been attempted yet, a positive value means the retrieve was successful (slay), and a negative value means the retrieve failed — and in that case the value is literally the error code of the call 😭
• file — the file object. and this one's doing double duty, so pay attention:
  • for retrieve: [OUT] — the callback sets this to the new file 💖
  • for other ops: [IN] — the caller sets this to the file being operated on 🫶
• serialized_data — the opaque u64 handle. preserve/prepare/freeze are allowed to update this field 👑
• private_data — private data for the file, used to hold runtime state that is not preserved. it gets set by the handler's .preserve callback, and — important — it must be freed in the handler's .unpreserve callback. don't leave it hanging bestie 💀

🦋 Description 🦋

this structure bundles all the parameters for the file operation callbacks — one cute little package, everything inside 🎁
