STRUCT KMSG_DUMP_DETAIL(9)

💅 struct kmsg_dump_detail(9) — like, the kernel crash detail era ✨

okay so bestie, this one is from the Kernel API Manual, section 9, and it's genuinely such a little icon. it's not a function, it's not a syscall, it's a struct — a whole vibe container. and its job? holding onto the deets of a kernel crash. yes ma'am, we're getting intimate with the collapse 💀

---

✨ NAME ✨

struct kmsg_dump_detail — kernel crash detail 🫶

like literally the little info packet that tells you why everything went sideways. no cap.

---

🦋 SYNOPSIS 🦋

struct kmsg_dump_detail {
    enum kmsg_dump_reason reason;
    const char *description;
 };

look at her. two members. minimal. iconic. she ate and left absolutely no crumbs 👑

---

🎀 Members 🎀

• reason — the reason for the crash, see kmsg_dump_reason. this is the main character field fr fr, it's the whole "so why are we here" of the situation 😭 it's an enum kmsg_dump_reason, so it's not just vibes, it's a proper typed vibe check.
• description — optional short string, to provide additional information. key word: optional, bestie 🙈 it's a const char *, so it's a pointer to a short little string that gives you extra context. if reason is the headline, description is the sub-tweet. lowkey obsessed.

🌸 SEE ALSO 🌸

• Kernel file ./include/linux/kmsg_dump.h
• struct kmsg_dump_iter(9)
• struct kmsg_dumper(9)

go read those if you want the full lore, iykyk 💜 the header file is where all the siblings live, and kmsg_dump_iter(9) + kmsg_dumper(9) are literally her besties. group chat energy tbh 🧚

---

heads up bestie: description being optional is not me being cute, that's straight from the page. don't come for me if you deref a NULL. 💅

✨ that's the whole page, mwah ✨ this gem lives in ./include/linux, and the version on the street is from October 2026 — so mark your calendars, the manual itself says struct kmsg_dump_detail(9) and honestly? she deserves the credit. slay 💖🎀🦋
