VM_MAP_SIMPLIFY_ENTRY(9)

✨ VM_MAP_SIMPLIFY_ENTRY ✨

ok so bestie, welcome to the Kernel Developer's Manual, section 9 — this is the page for vm_map_simplify_entry, and honestly? it's giving tiny function, huge responsibility 🫶

🌸 NAME 🌸

vm_map_simplify_entry — simplify a vm_map_entry 💅

🎀 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 🦋

ok so here's the tea ☕ — vm_map_simplify_entry() takes the entry you hand it and simplifies it by merging it with either neighbour. that's it, that's the job, and it does it flawlessly no cap 💅

⚠️ but listen — the map must be locked upon entry. like, locked locked. do not walk in there unlocked, i am begging 🙈

this function also has the ability to merge with both neighbours. overachiever behaviour, honestly. we love to see it 👑

and the best part? vm_map_simplify_entry() guarantees that the entry you passed in remains valid — although possibly extended. so your pointer is safe, it just might be... bigger now. glow up fr fr ✨
