✨ NAME ✨

check_short_pattern — [GENERIC] check if a pattern is in the buffer 🦋

---

🎀 SYNOPSIS 🎀

int check_short_pattern (uint8_t *buf , struct nand_bbt_descr *td );

---

💖 ARGUMENTS 💖

• buf — the buffer we're gonna search through, aka the lil haystack 🔍
• td — the search pattern descriptor, aka the thing that tells us what we're looking for 👑

---

🌈 DESCRIPTION 🌈

So here's the tea: this one checks for a pattern at the given place. Literally that's it, that's the whole job 💅

It's used to search bad block tables and good / bad block identifiers — so if you're deep in NAND land, this is your girl.

It's the same as check_pattern, but with no optional empty check. that's the one difference, periodt.
