🌸 SYNOPSIS 🌸

void radix_tree_iter_tag_clear (struct radix_tree_root *root , const
struct radix_tree_iter *iter , unsigned int tag );

Three args, one vibe check, zero return value (it's void, she doesn't do receipts 💅).

🦋 ARGUMENTS 🦋

• root — the radix tree root 🌳 like, the whole tree. the mothership. the source of truth.
• iter — iterator state 🎀 this is you telling her where you're at, bestie. she needs the context.
• tag — the tag to clear 🏷️ the one getting ✨ removed ✨. bye girl.

fr fr: peep the const on iter — she's reading your state, not messing with it 🙈
