📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

lpfc_fabric_block_timeout — the handler function for the fabric block timer bestie ✨ (yes that's the whole name, and yes it's a mouthful, we love her anyway)

Manual page: lpfc_fabric_block_timeout(9) — Kernel API Manual energy, no cap 💅

🌸 SYNOPSIS 🌸

void lpfc_fabric_block_timeout (struct timer_list *t );

That's it. That's the whole vibe. One function, one arg, zero drama 🎀

🦋 ARGUMENTS 🦋

  • t — the timer context, and it's literally the key to the whole thing because you use it to obtain the lpfc hba. So like, don't lose it, ok? 🫶

✨ DESCRIPTION ✨

okay so picture this: the fabric iocb block timer has officially run out of patience and it fires, right? This routine is the one that gets invoked after that timeout, and she does NOT show up empty-handed 🔥

First thing she does: she posts the fabric iocb block timeout event by setting the WORKER_FABRIC_BLOCK_TMO bit to work port event bitmap. Iconic. Very demure, very mindful 🌸

Then she invokes the lpfc_worker_wake_up routine to wake up the worker thread — because somebody has to actually do the work and it is not going to be the timer 💅

And the whole point of that? It's for the worker thread to invoke the lpfc_unblock_fabric_iocbs on the posted event WORKER_FABRIC_BLOCK_TMO. So like — the timer pokes the bitmap, the worker gets woken up, and the worker handles the unblocking. Teamwork makes the dream work, periodt 👑

And now, the guest list. It's long. It's giving "everyone's invited". Do not scroll past her, she worked hard on this 💀

okay that's the whole page, you made it to the bottom, I'm so proud of you 🥹

cute little sign-off time: this one lives in ./drivers/scsi/lpfc, it's dated October 2026, and it answers to lpfc_fabric_block_timeout(9) 🎀 go forth and unblock those fabric iocbs, bestie 💜
