traverse(9)

okay bestie, say hi to traverse(9) from the Kernel API Manual 💖✨ this one's short but it's got main-character energy.

🌸 NAME 🌸

traverse — traverse a single block map tree. that's the assignment, no cap 💅

🌈 SYNOPSIS 🌈

here's the whole signature, exactly as it's giving:

void traverse (struct cursor *cursor );

🦋 ARGUMENTS 🦋

• cursor — a cursor that's tracking traversal progress. like the little progress tracker for the whole operation 🫶

💖 DESCRIPTION 💖

okay so this is the recursive heart of the traversal process. periodt. the way it's the recursive core? iconic behavior, honestly 🔥👑
