ubi_dbg_is_bad_hdr_ebadmsg(9)

💖 NAME 💖

okay so bestie, this is the ubi_dbg_is_bad_hdr_ebadmsg(9) page from the Kernel API Manual — manual name folded in near the top, exactly as requested, and it's giving very niche debug-helper main character energy ✨

• ubi_dbg_is_bad_hdr_ebadmsg — if it is time to emulate a bad header with ECC error. That's the name, that's the vibe, no cap.

---

✨ SYNOPSIS ✨

Here's the signature, copied with love and zero edits:

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

---

🌸 ARGUMENTS 🌸

• ubi — UBI device description object. Essential. Iconic. We love a device description object.
• caller — the page literally says -- undescribed --, so that's all the lore we're getting 😭 No invented backstory, bestie, fr fr.

---

🎀 DESCRIPTION 🎀

Returns true if a bad header with ECC error should be emulated, otherwise returns false. That's the whole vibe check: bad header + ECC error emulation time? true. Otherwise? false. Simple, clean, slay.
