💅 range_in_vma(9) — the “is this range even in this VMA?” vibe check ✨

okay so bestie, we’re in the Kernel API Manual (section 9), and this one is range_in_vma(9). The whole mood? “is the specified [@start, @end) range a subset of the VMA?” It’s giving tiny but mighty. No cap. 🫶

🌸 NAME 🌸

range_in_vma — is the specified [@start, @end) range a subset of the VMA? 💖

✨ SYNOPSIS ✨

okay, here’s the exact signature, bestie — copy it, don’t fumble it:

       bool range_in_vma (const struct vm_area_struct *vma , unsigned long
       start , unsigned long end );

🎀 ARGUMENTS 🎀

  • vma — the VMA against which we want to check [start, end). she’s the main character here. 👑
  • start — the start of the range we wish to check. like, where the range begins. 🌸
  • end — the exclusive end of the range we wish to check. yes, exclusive — she does not include herself. 💅

💖 RETURN 💖

true if [start, end) is a subset of [vma->vm_start, vma->vm_end), false otherwise. that’s the tea. ☕✨
