finish_updating(9)

finish_updating 💅

okay so bestie, welcome to the finish_updating(9) page from the Kernel API Manual — it's giving kernel continuation energy, but make it group chat. Stay with me, it's short and iconic. ✨

✨ NAME ✨

finish_updating — process the result of a UDS update performed by the agent for the lock. That's the whole assignment, no cap. 💅

🌸 SYNOPSIS 🌸

void finish_updating (struct vdo_completion *completion );

🎀 ARGUMENTS 🎀

• completion — the completion of the data_vio that performed the update. That's the one we're handing over. 🫶

🦋 DESCRIPTION 🦋

This continuation is registered in start_querying. Literally that's the tea: it's a continuation, and start_querying is where it gets registered. Keep that in mind and you're slaying. ✨
