✨ clear_update_marker(9) ✨

okay bestie, so this one's from the Kernel API Manual, and it's literally about clearing the update marker. let's get into it 💅

🌸 NAME 🌸

clear_update_marker — clears the update marker, periodt.

---

🦋 SYNOPSIS 🦋

int clear_update_marker (struct ubi_device *ubi , struct ubi_volume *vol
, long long bytes );

like, that's the whole signature, no cap ✨

---

🎀 ARGUMENTS 🎀

• ubi — the UBI device description object, aka the whole vibe of the device 🫶
• vol — the volume description object, the specific volume we're doing this for
• bytes — the new data size, in bytes. yes, long long, she's got range 💖

---

🔥 DESCRIPTION 🔥

so this function clears the update marker for volume vol, sets the new volume data size, and clears the "corrupted" flag — but heads up, the corrupted-flag part is static volumes only, bestie, don't forget 🙈

it returns zero in case of success and a negative error code in case of failure. simple as that, iykyk 💀
