iowait_sdma_add(9)

🌸 NAME 🌸

okay so bestie, welcome to iowait_sdma_add(9) from the Kernel API Manual — yes, the manual name is getting folded in right here, we're not doing the boring header-copy thing 💅

iowait_sdma_add — add count to pending. That's the whole name vibe: add count to pending, periodt. ✨

✨ SYNOPSIS ✨

Like, the signature is right here, copy-paste exact:

void iowait_sdma_add (struct iowait *wait , int count );

It's giving void, so no return value to stress about 😌

🎀 ARGUMENTS 🎀

• wait — the iowait structure. That's the whole description the docs gave us, no cap.
• count — bestie, the manual literally says -- undescribed -- 😭 and I'm not gonna invent lore for it. That's the tea.
