smc_llc_add_pending_send(9)

🌸 NAME 🌸

okay so bestie, this is the smc_llc_add_pending_send(9) page from the Kernel API Manual — and it’s literally giving “add LLC control message to pending WQE transmits” ✨ no cap.

🦋 SYNOPSIS 🦋

int smc_llc_add_pending_send (struct smc_link *link , struct smc_wr_buf **wr_buf , struct smc_wr_tx_pend_priv **pend );

🎀 ARGUMENTS 🎀

• link — pointer to the SMC link used for sending the LLC control message 💌
• wr_buf — out variable returning a pointer to the work request payload buffer 🫶
• pend — out variable returning a pointer to the private pending WR tracking. It’s the context the transmit complete handler will get 👀

💅 DESCRIPTION 💅

So like, this function reserves and pre-fills an entry for a pending work request send/tx. The mid-level smc_llc_send_msg uses it to get ready for the later actual send/tx — main character prep energy, honestly 👑.

Heads up though: it can sleep due to smc_get_ctrl_buf (if you’re not in softirq context). So don’t be caught snoozing where snoozing is not allowed 😭💀.

⭐ RETURN ⭐

0 on success, otherwise an error value. That’s the vibe check, periodt 💅.
