ubi_dbg_is_write_failure(9)

💅 ubi_dbg_is_write_failure(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a little debug helper from the UBI world and honestly it's giving "tiny function, big job" energy ✨

---

🌸 NAME 🌸

ubi_dbg_is_write_failure — literally just tells you if it is time to emulate a write failure. no cap, that's the whole gig 🎀

---

🦋 SYNOPSIS 🦋

bool ubi_dbg_is_write_failure (const struct ubi_device *ubi );

so you call it like that, it hands you back a bool, and you pass in a pointer to a const struct ubi_device. iconic signature, no notes 💅

---

✨ ARGUMENTS ✨

• ubi — the UBI device description object 🫶 that's it, that's the one thing it wants from you

---

💖 DESCRIPTION 💖

Returns true if a write failure should be emulated, otherwise returns false.

that's literally it bestie — it's a yes/no vibe check on whether the debug layer should fake a write failure right now 🔥 true = go ahead and pretend the write failed, false = nah, we're good 🌈

no side quests, no surprises, just a boolean and a dream 😭
