okay so bestie, welcome to the Kernel API Manual page for check_create - [GENERIC] create and write bbt(s) if necessary ✨.

✨ SYNOPSIS ✨

int check_create (struct nand_chip *this , uint8_t *buf , struct
       nand_bbt_descr *bd );

🎀 ARGUMENTS 🎀

• this — the NAND device. literally the device we're working with 🫶
• buf — temporary buffer, just a lil scratch space 😭
• bd — descriptor for the good/bad block search pattern, the vibe check for blocks 💅

🦋 DESCRIPTION 🦋

okay so here's the tea: check_create checks the results of the previous call to read_bbt and creates / updates the bbt(s) if necessary. no cap ✨.

Creation is necessary if no bbt was found for the chip/device. Update is necessary if one of the tables is missing or the version nr. of one table is less than the other. periodt 💅.
