💅 svc_rdma_check_pull_up(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for svc_rdma_check_pull_up — yes that's the function, yes it's a whole vibe, and yes we're gonna get through it together 🫶

✨ NAME ✨

svc_rdma_check_pull_up — determine whether to use pull-up 👑

like, the whole gig is answering one question: are we pulling up or not? and she will absolutely tell you. no cap.

🌸 SYNOPSIS 🌸

int svc_rdma_check_pull_up (const struct svcxprt_rdma *rdma , const
       struct svc_rdma_send_ctxt *sctxt , const struct svc_rdma_pcl *write_pcl
       , const struct xdr_buf *xdr );

four args, one int coming back at you. it's giving "small function, big responsibilities" honestly 💀

🦋 ARGUMENTS 🦋

  • rdma — the controlling transport. she's the main character here, the one running the whole show 🌈
  • sctxt — the send_ctxt for the Send WR. yeah, that Send WR. she's got the context, she's holding it down 💜
  • write_pcl — the Write chunk list provided by the client. the client handed it over, so we're working with it 🎀
  • xdr — the xdr_buf containing the RPC message to transmit. it's the actual message, the payload, the moment ⭐

🔥 RETURN 🔥

so here's the tea on what she gives back 🍓

  • 1 — pull-up must be used. okay so we're pulling up, periodt 💅
  • 0 — pull-up is not needed. we're chill, we're good, no pulling up today 🙈
  • -E2BIG — the reply is too large to be pulled up 😭 like literally too big. can't be done. the audacity of this reply fr fr
