increment_generation(9)

💅 increment_generation(9) — Kernel API Manual 💅

🎀 NAME 🎀

increment_generation — Increment the flush generation in a logical zone.

✨ SYNOPSIS ✨

void increment_generation (struct vdo_completion *completion );

🫶 ARGUMENTS 🫶

• completion — the flusher, but as a completion. That’s the whole arg, bestie.

🌸 DESCRIPTION 🌸

Okay so: if there are more logical zones, it goes on to the next one; otherwise, it prepares the physical zones.

This callback is registered both in notify_flush and in itself. Lowkey iconic behavior, ngl.
