srpt_get_send_ioctx(9)

💖 NAME 💖

heyyy bestie welcome to the Kernel API Manual, section 9, where we talk about srpt_get_send_ioctx — and what it does is literally just this: it obtains an I/O context for sending to the initiator. that's the whole assignment. no cap. 🫶

---

✨ SYNOPSIS ✨

okay so this is the shape of it, and yes you're gonna want to keep it exactly like this:

struct srpt_send_ioctx * srpt_get_send_ioctx (struct srpt_rdma_ch *ch );

you hand it a ch, it hands you back a struct srpt_send_ioctx *. iconic behavior honestly. 💅

---

🎀 ARGUMENTS 🎀

• ch — the SRPT RDMA channel. that's it. that's the entire argument list. one (1) bestie. 🦋

lowkey a flex that one tiny function has this many friends. the way that srpt is a whole ecosystem. 🌸

okay that's the page!! mwah, go read the source, and remember where this came from: ./drivers/infiniband/ulp/srpt, dated October 2026, and the page itself is srpt_get_send_ioctx(9). periodt. 🎀✨🦋
