vdo_resume_flusher(9)

💖 vdo_resume_flusher(9) 💖

okay bestie, so this is a page straight out of the Kernel API Manual — it's vdo_resume_flusher(9), and like the name literally says, we're waking a flusher back up after it's been put to sleep. nap time's over, queen 👑

✨ NAME ✨

vdo_resume_flusher — resume a flusher which has been suspended.

🌸 SYNOPSIS 🌸

void vdo_resume_flusher (struct flusher *flusher , struct vdo_completion
*parent );

no cap, that's the whole signature. two args, no return, we move 💅

🎀 ARGUMENTS 🎀

• flusher — the flusher to resume. this is the sleepy little guy getting its whole life back 🦋
• parent — the completion to finish when the flusher has resumed. so like, once the flusher's up and running, this completion gets finished — that's the deal 🤝
