💅 ubi_dbg_is_read_failure(9) — the kernel API manual bestie

okay so bestie, welcome to the Kernel API Manual entry for ubi_dbg_is_read_failure. no cap, this one's a little debug-flavored gem and you're gonna get it instantly. ✨

🎀 NAME 🎀

ubi_dbg_is_read_failure — asks the universe: is it time to emulate a read failure? 👀

---

⭐ SYNOPSIS ⭐

bool ubi_dbg_is_read_failure (const struct ubi_device *ubi , unsigned
int caller );

literally the whole signature right there, character for character, don't @ me. 🫶

---

🦋 ARGUMENTS 🦋

• ubi — the UBI device description object. this is the main character of the whole situation. 👑
• caller — -- undescribed --. yeah. the original manpage just did not say. it's giving mystery, it's giving "you'll find out," and honestly? iconic. 🙈

---

🌸 DESCRIPTION 🌸

so here's the vibe check: this function returns true if a read failure should be emulated. otherwise it returns false. periodt. that's the whole job, and it does it flawlessly. 💅

no extra lore, no plot twists — if you were hoping for a third option, sorry bestie, it's a bool, there's only the two. 😭

🍓 tiny reminder bestie: this is debug territory — emulated failures are on purpose, so don't panic when they show up.

okay that's the page!! mwah!! 💖
