shpchp_pushbutton_thread(9)

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

okay so this is shpchp_pushbutton_thread, straight out of the Kernel API Manual, and it's honestly such a little workhorse 🫶 it's the function that shows up when a pushbutton on a hotplug slot has stuff to deal with. short page, big main character energy. let's get into it ✨

---

🌸 NAME 🌸

shpchp_pushbutton_thread — handle pushbutton events 🎀

like, that's the whole job. pushbutton events. handled. periodt.

---

⭐ SYNOPSIS ⭐

void shpchp_pushbutton_thread (struct work_struct *work );

that's it, that's the signature, copy it exactly, no cap 💅

---

🦋 ARGUMENTS 🦋

• work — the struct work_struct that's gonna get handled. that's the whole parameter list, she's lowkey minimal and we respect it 🙈

---

💖 DESCRIPTION 💖

okay so picture this: it's a scheduled procedure — the kernel queued her up, and her entire purpose in life is handling the blocking stuff for the pushbuttons. all the stuff that can't just happen inline, the stuff that has to wait its turn. she's the one who deals with it 🧚

and then — and this is the iconic part — she handles all the pending events and exits. all of them. not some, not most. all. then she's out. no lingering, no drama, no "just one more thing". she ate and she left the group chat 👑

so yeah 🍓 that's the page. ./drivers/pci/hotplug is where she lives, this manual's dated October 2026, and honestly? iconic of her. go handle those events bestie, and remember: handle all the pending ones, then exit. no notes. mwah 💜✨
