STRUCT PSTORE_ZONE(9)

💾 struct pstore_zone(9) — the Kernel API Manual, bestie edition 💾

okay so picture this: you're deep in the struct pstore_zone(9) man page from the Kernel API Manual and honestly? it's giving "one little buffer, but make it official." this is the page for a single stored buffer bestie, and yes we're gonna read the whole thing together, no skipping 💅

✨ NAME ✨

struct pstore_zone — literally just one single stored buffer 🎀

---

🌸 SYNOPSIS 🌸

here's the whole shape of her, no cap, copy it exactly:

struct pstore_zone {
    loff_t off;
    const char *name;
    enum pstore_type_id type;
    struct psz_buffer *buffer;
    struct psz_buffer *oldbuf;
    size_t buffer_size;
    bool should_recover;
    atomic_t dirty;
 };

🦋 MEMBERS 🦋

okay bestie, let's meet the whole cast 💖

• off — the zone offset of storage. like, where she sits in the storage, fr fr.
• name — front-end name for this zone. that's her government name ✨
• type — front-end type for this zone. her whole vibe category, iykyk.
• buffer — pointer to the data buffer managed by this zone. she's literally in charge of it 👑
• oldbuf — pointer to the old data buffer. the throwback version, the archival queen 🙈
• buffer_size — bytes in buffer->data. count 'em 💅
• should_recover — whether this zone should recover from storage. lowkey a big deal.
• dirty — whether the data in buffer dirty. (that's the original phrasing, we do not fix it, we simply report it 🫶)

⭐ Description ⭐

zone structure in memory. that's it, that's the whole description, she's short and iconic 🌈
