doc_get_erase_count(9)

🌸 NAME 🌸

Welcome to doc_get_erase_count(9), straight from the Kernel API Manual — this one gets the block erase count, bestie. It's giving “how many times has this block been erased?” energy. 💅

✨ SYNOPSIS ✨

int doc_get_erase_count (struct docg3 *docg3 , loff_t from );

💖 ARGUMENTS 💖

• docg3 — the device. Like, the literal struct docg3 * you're passing in, no cap. 🫶
• from — the offset in which the block is. This is your “where does this block even live” coordinate. 🎯

🦋 DESCRIPTION 🦋

Okay so doc_get_erase_count gets the number of times a block was erased. The number it returns is the maximum of the erase times between the first plane and the second plane — and yeah, those should normally be equal, periodt. 💫

Returns the number of erases, or -EINVAL or -EIO on error. 😭
