💖 NAME 💖

okay so bestie, welcome to check_lpt_crc(9) from the Kernel API Manual — this one checks that LPT node crc is correct. periodt. ✨

✨ SYNOPSIS ✨

int check_lpt_crc (const struct ubifs_info *c , void *buf , int len );

🎀 ARGUMENTS 🎀

• c — UBIFS file-system description object
• buf — buffer containing node
• len — length of node

🦋 DESCRIPTION 🦋

okay so here's the tea: this function returns 0 on success and a negative error code on failure. that's the whole vibe check, no cap. 💖
