ssh_ptl_should_fail_write(9)

💅 ssh_ptl_should_fail_write(9) — the Kernel API Manual page, bestie edition 🎀

Okay so this is a page from the Kernel API Manual, and it's literally titled ssh_ptl_should_fail_write, bestie. Let's get into it ✨

---

🌸 NAME 🌸

ssh_ptl_should_fail_write — an error injection hook whose whole job is to make serdev_device_write() fail. Yes, on purpose. Iconic behavior, no cap 💅

---

🦋 SYNOPSIS 🦋

int ssh_ptl_should_fail_write (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments, bestie. None. Zero. The function said "I need nothing from you" and honestly? Respect 🫶

---

✨ DESCRIPTION ✨

This is the hook you use to simulate errors in serdev_device_write when transmitting packets. It's giving "let's break it on purpose so we can test stuff" energy 😭🔥

And that's the whole vibe, bestie 💖 This was from the Linux Kernel, dated October 2026, and the original page footer had ./drivers/platform/surface/agg... on the left with October 2026 and ssh_ptl_should_fail_write(9) hanging out at the bottom. Slay 🌈⭐
