💅 NAME 💅

vmw_find_last_diff — find the last difference between dst and src. Okay so this little cutie is vmw_find_last_diff(9) from the Kernel API Manual, and it is literally giving “find the last difference” energy. 🦋

✨ SYNOPSIS ✨

ssize_t vmw_find_last_diff (const u8 *dst , const u8 *src , size_t size
       , size_t granularity );

🎀 ARGUMENTS 🎀

• dst — the destination address, aka where the bytes are headed. 💖
• src — the source address, aka where the bytes are coming from. ✨
• size — number of bytes to compare. slay, a size. 📏
• granularity — the granularity needed for the return value, in bytes. 🎯

💫 RETURN 💫

It returns the offset from find start where the last difference was encountered, in bytes. 🔥 And if no difference was found? It returns a negative value. Periodt. 💀
