💅 svc_rdma_sendto(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for svc_rdma_sendto — yes that's the function name AND the manual page name, we love a name that does double duty ✨

🌸 NAME 🌸

svc_rdma_sendto — Transmit an RPC reply 🚀

✨ SYNOPSIS ✨

int svc_rdma_sendto (struct svc_rqst *rqstp );

🎀 ARGUMENTS 🎀

  • rqstp — the processed RPC request, whose reply XDR is already sitting pretty in ::rq_res. like it's already packed, no cap, we're not re-encoding anything here 🫶

🦋 DESCRIPTION 🦋

Any resources still associated with rqstp are released upon return. periodt, that's the rule — you come back from this call and everything tied to that request is gone 💀

If no reply message was possible, the connection is closed. yep, that's it, the whole vibe check fails and the connection goes bye 🫠

🔥 RETURN 🔥

  • 0 — an RPC reply has been successfully posted 🎉 slay
  • -ENOMEM — a resource shortage occurred (connection is lost) 😭
  • -ENOTCONN — posting failed (connection is lost) 💀
ngl bestie, two of the three outcomes mean the connection is gone. so like… check that return value, fr fr 🙈
