lpfc_els_ret...elay_handler(9)

💅 lpfc_els_retry_delay_handler — Kernel API Manual 👑

ok so real talk, this is a page from the Kernel API Manual (that's the manual name, bestie, it's not a section you read, it's the whole vibe of the doc set ✨). And the header up top is lowkey too long for its own good, so it gets truncated and shows up looking like lpfc_els_ret...elay_handler(9) — the ... is not a mystery, it's just the page name being a whole paragraph 💀. The actual function is lpfc_els_retry_delay_handler, and we're about to get into it.

🌸 NAME

lpfc_els_retry_delay_handler — the work thread handler for the ndlp delayed function. that's the whole name tag, periodt 💅

---

✨ SYNOPSIS

void lpfc_els_retry_delay_handler (struct lpfc_nodelist *ndlp );

one function, one pointer, zero drama. love that for us 🫶

---

🎀 ARGUMENTS

• ndlp — a pointer to a node-list data structure. that's it, that's the arg, she takes exactly one (1) pointer to a struct lpfc_nodelist and minds her business ✨

---

🦋 DESCRIPTION

okay so here's the tea ☕ — this routine is the worker-thread handler for processing the ndlp's delayed event(s), and those events were posted by the lpfc_els_retry_delay routine (she's the one who queued them up, this function is the one who actually shows up to do the work 💅).

what does it do though? literally just two things, no cap:

1. it retrieves the last ELS command from the associated ndlp 🎀
2. it invokes the proper ELS function according to that delayed ELS command, so the command gets retried 🔥

so it's the retry-delivery girlie. the delayed work said "bestie handle this later," and this is the later. iconic behavior, honestly 👑

and that's the page!! shoutout to the source tree at ./drivers/scsi/lpfc — that's the version/path stamp, and the date on the whole thing is October 2026 📅. so she's from the future, she's in drivers/scsi/lpfc, and she's only here to retry your delayed ELS command. go off, queen 💅👑🦋
