xprt_wait_for_buffer_space(9)

💅 xprt_wait_for_buffer_space — Kernel API Manual (section 9) 🦋

okay so bestie, you found it — the xprt_wait_for_buffer_space page from the Kernel API Manual, section 9. yes, that one. pull up a chair, grab a strawberry 🍓, and let's get into it.

---

✨ NAME ✨

xprt_wait_for_buffer_space — literally just wait for the transport output buffer to clear 🫶

---

🌸 SYNOPSIS 🌸

void xprt_wait_for_buffer_space (struct rpc_xprt *xprt );

that's the whole vibe. returns void, takes one pointer, no notes. 💅

---

🎀 ARGUMENTS 🎀

• xprt — the transport. that's it. that's the whole argument. main character energy 👑

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — note that we only set the timer for the case of RPC_IS_SOFT, because we don't in general want to force a socket disconnection due to an incomplete RPC call transmission. no cap, that's the whole rule. don't come for the socket unless it's soft. 🫶

fr fr, this is the only thing this page tells you — the timer is gated on RPC_IS_SOFT, and the reason is that forcing a disconnect over a half-sent RPC call is Not It. 🙈
