🫶 suspend_index(9) — Kernel API Manual 💅

okay so bestie, welcome to the suspend_index(9) page from the Kernel API Manual. This one is a tiny but iconic little function page, and its whole mission is suspending the UDS index prior to draining hash zones. That's the vibe. No cap. ✨

🌸 NAME 🌸

suspend_index — Suspend the UDS index prior to draining hash zones. That's literally the exact assignment, bestie. 🎀

📜 SYNOPSIS 📜

void suspend_index (void *context , struct vdo_completion *completion );

🎀 ARGUMENTS 🎀

• context — Not used. She's just there for the group photo; the page literally says "Not used."
• completion — The completion for the suspend operation. That's the actual handle for the suspend, bestie.

🦋 DESCRIPTION 🦋

Implements vdo_action_preamble_fn. That's it, periodt. That one line is the whole description, and I'm not adding extra lore. 💅
