mas_for_each_rev(9)

💖 NAME 💖

okay bestie, this is mas_for_each_rev(9) from the Kernel API Manual — it's the one that will Iterate over a range of the maple tree in reverse order. yes queen, reverse. 💅

✨ SYNOPSIS ✨

mas_for_each_rev (__mas , __entry , __min );

🎀 ARGUMENTS 🎀

• __mas — Maple Tree operation state (maple_state) — the operation-state bestie for the maple tree.
• __entry — Entry retrieved from the tree — the entry you got back from the tree.
• __min — minimum index to retrieve from the tree — the lowest index you're asking for.

🦋 DESCRIPTION 🦋

When returned, mas->index and mas->last will hold the entire range for the entry. that's the whole vibe: you get the entry, and those two fields carry the full range. 🫶

⚠️ NOTE ⚠️
