lpfc_poll_timeout(9)

💖 lpfc_poll_timeout — a lpfc_poll_timeout(9) situation 💖

okay bestie so this is the manual page for lpfc_poll_timeout(9) from the Kernel API Manual, and honestly? it's a little one. a tiny little function. but we're gonna give it the full main-character treatment anyway because that's just who we are 🎀

---

✨ NAME ✨

lpfc_poll_timeout — bestie this one restarts the polling timer. that's it. that's the whole vibe. ⏲️💅

---

🌸 SYNOPSIS 🌸

void lpfc_poll_timeout (struct timer_list *t );

look at her. no return value. just vibes and a timer pointer. iconic honestly 👑

---

🦋 ARGUMENTS 🦋

• t — the timer construct 🕰️ — this is where the lpfc_hba data structure pointer gets obtained, like it's pulling its whole identity out of the timer. slay.

---

💜 DESCRIPTION 💜

so here's the tea ☕ — this routine restarts the fcp_poll timer. not starts, *re*starts. we're in our encore era ✨

and when does that happen, you ask? it happens when FCP ring polling is enable and the FCP Ring interrupt is disable. lowkey a very specific little combo platter, but that's exactly the scenario she was built for. the way that she just quietly re-arms the timer while the interrupt is off... ngl it's giving underrated 🔥

okay so this section is long, bestie. like, genuinely long. she has a LOT of friends. we're talking a whole group chat of kernel functions. grab a snack 🍓 — here we go:

• the kernel file ./drivers/scsi/lpfc/lpfc_scsi.c 💾 — that's where she lives, that's her home turf, periodt.

bestie note: yes, __lpfc_get_device_data(9) has two underscores and yes we kept both. we are not out here editing names, that would be a crime 💀
