megaraid_sys...dmap_timeout(9)

💅 megaraid_sysfs_get_ldmap_timeout — a lil page from the Kernel API Manual

okay so bestie, welcome to megaraid_sys...dmap_timeout(9), straight out of the 🌸 Kernel API Manual 🌸. no cap, this one's short and sweet — it's literally one tiny timeout callback living its best life in the megaraid driver, and yes it has main character energy despite being like six lines of prose. let's get into it 🫶

---

✨ NAME ✨

megaraid_sysfs_get_ldmap_timeout — timeout handling for get ldmap 💫

---

🎀 SYNOPSIS 🎀

void megaraid_sysfs_get_ldmap_timeout (struct timer_list *t );

---

🦋 ARGUMENTS 🦋

• t — the timed out timer ⏰ like, the actual timer that just went "okay I'm done waiting" and fired this whole thing off.

---

🌈 DESCRIPTION 🌈

so here's the vibe: this is a timeout routine. its whole job is to recover and return control back to the application in case the adapter has stopped responding 😭 (yes, hardware can just ghost you like that, rude).

and how long do we wait before hitting the panic button? a timeout of 60 seconds for this command. the manpage says that "seems like a good value" — and honestly? slay. sixty seconds is giving patient-but-not-a-doormat. 💅

ngl, the entire point here is damage control. adapter goes quiet → timer fires → megaraid_sysfs_get_ldmap_timeout shows up and gets your app back on its feet instead of leaving it hanging forever. iconic behaviour, truly. 👑
