ENUM BLK_ZONE_TYPE(9)

💖 enum blk_zone_type(9) 💖

okay bestie, so this is a page from the Linux Kernel API Manual — like, straight out of the kernel docs — and it's about enum blk_zone_type. Yes, the whole page is literally just one enum, and honestly? She's small but she's doing a lot. ✨

🌸 NAME 🌸

enum blk_zone_type — the types of zones that are allowed in a zoned device 🎀

✨ SYNOPSIS ✨

enum blk_zone_type {
    BLK_ZONE_TYPE_CONVENTIONAL ,
    BLK_ZONE_TYPE_SEQWRITE_REQ ,
    BLK_ZONE_TYPE_SEQWRITE_PREF

};

🦋 Constants 🦋

• BLK_ZONE_TYPE_CONVENTIONAL — this zone has, like, no write pointer at all, and you can write to it randomly wherever you want, no rules 💅. Also, a zone reset does nothing to it — zero effect, no cap.
• BLK_ZONE_TYPE_SEQWRITE_REQ — this zone must be written sequentially, fr fr. No jumping around. 🙈
• BLK_ZONE_TYPE_SEQWRITE_PREF — this zone can be written non-sequentially. It's a preference, not a requirement — she's flexible like that 🧚

⭐ Description ⭐

And here's the important bit, bestie: any other value that's not defined up there is reserved and must be considered invalid. So like, don't be out here making up your own zone types, okay? 😭 The kernel will not be amused. 💀
