rvt_post_one_wr(9)

💅 NAME 💅

okay so bestie 💖, this is the rvt_post_one_wr(9) page from the Kernel API Manual — and the whole vibe is literally “post one RC, UC, or UD send work request.” That’s the name, that’s the assignment, periodt. ✨

🛠 SYNOPSIS 🛠

here’s the exact signature, copy it carefully so you don’t accidentally delete a comma 😭:

int rvt_post_one_wr (struct rvt_qp *qp , const struct ib_send_wr *wr ,
       bool *call_send );

🎀 ARGUMENTS 🎀

three little arguments, all iconic:

• qp — the QP to post on.
• wr — the work request to send.
• call_send — kick the send engine into gear.
