chain_busy(9)

🦋 chain_busy(9) — the Kernel API Manual moment 🦋

okay so bestie, welcome to chain_busy(9), straight out of the Kernel API Manual ✨. This is the little function that does a vibe check on your chain — like, is it still out here processing its last requests? 👀 That's literally the whole job. She's small, she's iconic, she's a one-liner in the source, and honestly? We respect her for it 💅.

💖 NAME 💖

chain_busy — check if the chain is still processing last requests 🫶

✨ SYNOPSIS ✨

int chain_busy (struct hinic_api_cmd_chain *chain );

🎀 ARGUMENTS 🎀

• chain — the chain you wanna check, bestie 🌸. That's it, that's the argument. Just hand over the chain and let her do her thing.

🔥 DESCRIPTION 🔥

The way this is so simple 😭 — it returns 0 on Success, and a negative value on Failure. That's the entire personality. No cap, no extra lore, no secret third return value. Zero means slay, negative means something went sideways 💀.

ngl, the manpage footer is lowkey serving truncated-path main character energy: <italic>./drivers/net/ethernet/huawei/...</italic> dated October 2026 ✨. So yeah — that's the source/version and the date, straight from the original, and chain_busy(9) is signing off 💖 see you in the next manpage, bestie 🎀🦋
