lpfc_poll_rearm_timer(9)

💅 lpfc_poll_rearm_timer(9) — like, the kernel API manual page, bestie

okay so this is a page from the Kernel API Manual (lpfc_poll_rearm_timer(9), section 9) and it's lowkey one of those tiny functions that does exactly one thing and does it slayfully. let's get into it ✨

---

🌸 NAME 🌸

lpfc_poll_rearm_timer — the routine that modifies the fcp_poll timer of an hba. that's it. that's the whole vibe check. 🎀

---

🦋 SYNOPSIS 🦋

void lpfc_poll_rearm_timer (struct lpfc_hba * phba );

no return value, no drama, just vibes. 👑

---

💖 ARGUMENTS 💖

• phba — the Hba for which this call is being executed. like, THE hba. the one and only. this function is so not doing anything without it. 🫶

---

✨ DESCRIPTION ✨

so here's the tea, bestie: this routine modifies the fcp_poll_timer field of phba by cfg_poll_tmo. iconic behaviour honestly.

and the default value of cfg_poll_tmo? 10 milliseconds. ten. ms. tiny little baby timeout. 🍓

fr fr the whole function is just "set the timer to cfg_poll_tmo" — no cap, that's the entire plot. and it ate. 💅
