🌸 mmu_interval_notifier_insert — NAME 💅

okay so bestie, this is mmu_interval_notifier_insert from the Kernel API Manual (the mmu_interval...ifier_insert(9) girlies know ✨) and it does exactly one iconic thing: Insert an interval notifier. that's it, that's the vibe. 🎀

✨ SYNOPSIS ✨

int mmu_interval_notifier_insert (struct mmu_interval_notifier
*interval_sub , struct mm_struct *mm , unsigned long start , unsigned
long length , const struct mmu_interval_notifier_ops *ops );

like, five args, one int return, we love a clean signature 🫶

🦋 ARGUMENTS 🦋

  • interval_sub — the interval subscription you're registering. the main character of this whole operation 💅
  • mm — the mm_struct you're attaching to. your plus-one fr fr
  • start — the starting virtual address you wanna monitor 👀
  • length — how long the range you're monitoring is. like how far the vibes extend 🌈
  • ops — the interval notifier operations that get called on matching events. these are the ones on speed dial when something goes down 🔥

💖 DESCRIPTION 💖

so this function subscribes the interval notifier for notifications from the mm. and like, upon return, the ops related to mmu_interval_notifier will be called whenever an event that intersects with the given range occurs. intersecting events? she's always in the mix 💀

ngl there's a lil catch bestie: upon return, the range_notifier may not be present in the interval tree yet. 😭 so the caller must use the normal interval notifier read flow via mmu_interval_read_begin to establish SPTEs for this range. it's giving "you have to do your part too," no cap. 🫶
