✨ NAME ✨

struct kmsg_dumper — the kernel crash message dumper structure 🫶

---

🌸 SYNOPSIS 🌸

ok here's the whole shape of it, character for character, don't touch:

struct kmsg_dumper {
    struct list_head list;
    void (*dump)(struct kmsg_dumper *dumper, struct kmsg_dump_detail
*detail);
    enum kmsg_dump_reason max_reason;
    bool registered;
 };

---

🎀 Members 🎀

• list — your entry in the dumper list, and it's private, so like. mind your business bestie 🙈
• dump — this is the call into the dumping code, which will retrieve the data through the record iterator. it's giving main character energy, honestly 💅
• max_reason — the filter for the highest reason number that should be dumped ✨
• registered — a flag that specifies if this is already registered. yes she's a bool, yes she's doing her best 👑
