okay so bestie, welcome to the Kernel API Manual — this one's a kernel function, section 9, and it's lowkey kind of iconic in a scary way 🫶

✨ NAME ✨

mf_dax_kill_procs — literally collects and kills the processes that are using this file range. yes. that's the whole job. no cap 💅

---

🎀 SYNOPSIS 🎀

int mf_dax_kill_procs (struct address_space *mapping , pgoff_t index ,
       unsigned long count , int mf_flags );

🦋 ARGUMENTS 🦋

• mapping — the address_space of the file that's in use. it's giving "who's the file in question" energy 📂
• index — the starting pgoff of the range inside the file. where the drama begins ✨
• count — how long the range is, measured in units of PAGE_SIZE. yes, PAGE_SIZE, not bytes, she has her own units 💅
• mf_flags — the memory failure flags. the vibes/parameters of the whole operation 🚩
