📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

kunit_vm_mmap — bestie, this one allocates a vm_mmap() area that KUnit keeps an eye on for you ✨

🦋 SYNOPSIS 🦋

unsigned long kunit_vm_mmap (struct kunit *test , struct file *file ,
unsigned long addr , unsigned long len , unsigned long prot , unsigned
long flag , unsigned long offset );

🌸 ARGUMENTS 🌸

  • test — the test context object, aka where all your test gossip lives 🫶
  • file — a struct file pointer to map from, if any
  • addr — the desired address, if any
  • len — how many bytes you're allocating, so like, the size of the vibe
  • prot — the mmap PROT_* bits
  • flag — the mmap flags
  • offset — the offset into the file to start mapping from, no cap

✨ DESCRIPTION ✨

Okay so see vm_mmap for more information 💅 — that's the whole mood, go look at vm_mmap, it's giving source of truth.
