💅 enum psz_flush_mode(9)

okay bestie, welcome to the Kernel API Manual — this one's a lil enum from the kernel, and honestly? it's giving "small but mighty" 🎀

✨ NAME ✨

🦋 SYNOPSIS 🦋

enum psz_flush_mode {
    FLUSH_NONE ,
    FLUSH_PART ,
    FLUSH_META ,
    FLUSH_ALL

};

that's the whole vibe. four constants, zero drama ✨

🎀 Constants 🎀

• FLUSH_NONE — do not flush to storage, but do update the data in memory 🧠✨ (so like, it's living in RAM, main character energy, not on disk yet)
• FLUSH_PART — just flush part of the data to storage, and that part includes the meta data 🫶
• FLUSH_META — just flush the meta data of the zone to storage, nothing more, no cap 💅
• FLUSH_ALL — flush all of the zone. the whole thing. periodt 🔥
