VM_MAP_SIMPLIFY_ENTRY(9)

✨ NAME ✨

okay so welcome to VM_MAP_SIMPLIFY_ENTRY(9), bestie 💖 — this is the Kernel Developer’s Manual page for vm_map_simplify_entry — simplify a vm_map_entry. Slay. 🎀

---

🌸 SYNOPSIS 🌸

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

void
vm_map_simplify_entry(vm_map_t map, vm_map_entry_t entry);

---

🦋 DESCRIPTION 🦋

So vm_map_simplify_entry() is literally the glow-up function for the given entry: it simplifies that entry by merging with either neighbour. Iconic behaviour, no cap. 💅

Vibe check first, bestie: the map must be locked upon entry. Like, lock it before you call this. That part is not optional. 🔥

This function also has the ability to merge with both neighbours. Lowkey overachiever energy, honestly. ✨

And the guarantee? This function guarantees that the passed entry remains valid, although possibly extended. So it might get bigger, but it stays valid — periodt. 👑
