VM_MAP_REMOVE(9)

💖 VM_MAP_REMOVE — the kernel dev manual, bestie edition 💖

okay so this is VM_MAP_REMOVE(9), from the Kernel Developer's Manual, and it's giving "I delete things and I'm chill about it." Let's get into it ✨

---

🌸 NAME 🌸

vm_map_remove — remove a virtual address range from a map

Like, literally. Range in, range gone. No cap. 💅

---

🎀 SYNOPSIS 🎀

#include <sys/param.h>
#include <vm/vm.h>
#include <vm/vm_map.h>

int
vm_map_remove(vm_map_t map, vm_offset_t start, vm_offset_t end);

Three headers, one function, zero drama. She's low maintenance fr fr 🫶

---

🦋 DESCRIPTION 🦋

The vm_map_remove() function removes the given address range bounded by start and end from the target map.

That's it. That's the whole vibe. You hand her a map and two boundaries and she takes that slice of address space OUT. Bye. Gone. Not me being emotional about a memory range 😭

---

👑 IMPLEMENTATION NOTES 👑

• This is the exported form of vm_map_delete(9), which may be called by consumers of the VM subsystem. So like, vm_map_delete(9) is the backstage version and vm_map_remove() is the one with main character energy that everyone else gets to talk to. ✨
• The function calls vm_map_lock(9) to hold a lock on map for the duration of the function call. She locks the door, does her thing, and nobody's getting in mid-glow-up. 🔒💅

---

⭐ RETURN VALUES ⭐

The vm_map_remove() always returns KERN_SUCCESS.

Always. Not "usually", not "most of the time", not "depends on your moon sign". ALWAYS. She ate and left no crumbs, and there are no crumbs to report. 🔥
