lpfc_els_timeout(9)

📦 version 7.3.1, in nixpkgs unstable

💅 lpfc_els_timeout 💅

okay so bestie, welcome to lpfc_els_timeout(9), fresh out of the Kernel API Manual — this is the little timer callback that shows up when the ELS timer has had Enough™ and it's time to hand things off to the worker thread. she's short, she's sweet, she's iconic. let's get into it ✨

🌸 NAME 🌸

lpfc_els_timeout — handler funciton to the els timer

(and yes, "funciton" is literally how it's spelled in the source, we are keeping her, no cap 😭💖)

🦋 SYNOPSIS 🦋

void lpfc_els_timeout (struct timer_list *t );

🎀 ARGUMENTS 🎀

  • t — timer context used to obtain the vport. that's the whole vibe fr, it's the timer context and it's literally how we get our hands on the vport 🫶

💜 DESCRIPTION 💜

so here's the tea ☕ — this routine gets invoked by the ELS timer after timeout. like, the timer ran out, nobody's surprised, and now this function is on stage.

what does she do? she posts the ELS timer timeout event by setting the WORKER_ELS_TMO bit to the work port event bitmap. then she invokes the lpfc_worker_wake_up routine to wake up the worker thread. 💅

and here's the part people miss: it's for the worker thread to invoke the routine lpfc_els_timeout_handler to work on the posted event WORKER_ELS_TMO. so like — this function's whole job is the handoff, okay? she's not doing the work herself, she's the main character who delegates. 👑

the flow, laid out pretty:

  1. the ELS timer times out and calls lpfc_els_timeout with the timer context t
  2. the WORKER_ELS_TMO bit gets set on the work port event bitmap
  3. lpfc_worker_wake_up wakes up the worker thread
  4. the worker thread invokes lpfc_els_timeout_handler to work on the posted event WORKER_ELS_TMO

ate. no notes. 🍓

like I said — huge friend group, every single one invited, nobody left on read 🫶✨

ok that's the whole page bestie, love that for us 🌸

and that's a wrap! this lil masterpiece lives in ./drivers/scsi/lpfc and it's dated October 2026 — so go forth, set those bits, wake those worker threads, and slay 💅👑💖
