scmi_notification_quiesce(9)

💖 scmi_notification_quiesce(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil function with a big job and honestly it's giving "quietly holds the whole thing together" energy 👑

🌸 NAME 🌸

scmi_notification_quiesce — the girl who tells the notifications to chill and stop late-initializing 🛑

✨ SYNOPSIS ✨

void scmi_notification_quiesce(struct scmi_handle *handle);

🎀 ARGUMENTS 🎀

• handle — the handle that IDs the platform instance you're boutta quiesce 🫶 she's the main character here, no cap

🦋 DESCRIPTION 🦋

so here's the vibe 💅 this function prevents new late-init work from being queued at all — like, no new entries, we're closed — and then it waits for any late-init work that's already queued or straight-up running to finish before the transport channels get torn down 😭

basically: nobody new gets in, and everybody already inside gets to finish their thing before the lights go out. iconic behavior honestly 🔥
