✨ lpfc_cmpl_els_disc_cmd(9) ✨

okay so bestie, this is a page straight out of the Kernel API Manual, and it's all about one lil completion callback that does a LOT of heavy lifting for Discovery ELS cmds. sit down, grab a strawberry drink 🍓, and let's get into it 💅

🌸 NAME 🌸

lpfc_cmpl_els_disc_cmd — the Completion callback function for Discovery ELS cmd. that's it, that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

void lpfc_cmpl_els_disc_cmd (struct lpfc_hba *phba , struct lpfc_iocbq
*cmdiocb , struct lpfc_iocbq *rspiocb );

like, three pointers, one void, zero drama. slay ✨

💖 ARGUMENTS 💖

  • phba — pointer to lpfc hba data structure. (the hba in question, bestie 🫶)
  • cmdiocb — pointer to lpfc command iocb data structure. (the cmd iocb, iykyk)
  • rspiocb — pointer to lpfc response iocb data structure. (the response iocb — yes there's a difference, and yes it matters 💀)

🔥 DESCRIPTION 🔥

so this routine is a generic completion callback function for the Discovery ELS cmd. generic as in it's the go-to, the main character of callbacks 👑

currently it's used by the ELS command issuing routines for:

  • the ELS State Change Request (SCR) — lpfc_issue_els_scr
  • Exchange Diagnostic Capabilities (EDC) — lpfc_issue_els_edc
  • and the ELS RDF — lpfc_issue_els_rdf
and here's the part you can't skip, bestie: these commands will be retried once only for ELS timeout errors. one (1) retry. not two, not "however many feels right." once only, periodt. 💅

🌈 SEE ALSO 🌈

Kernel file ./drivers/scsi/lpfc/lpfc_els.c — and honestly the whole friend group shows up here, so let's do the roll call 🎤:

like, that's the whole squad. icon behavior honestly 👑💜

and that's the page!! mwah 💋 this lil gem lives in ./drivers/scsi/lpfc, it's dated October 2026, and yes it's still signed lpfc_cmpl_els_disc_cmd(9) — go be a completion callback icon bestie, ily 🎀🦋💖
