💅 octeon_flush_cache_page (the Kernel API Manual girlies know)

okay so bestie, welcome to octeon_flush_cache_page — a kernel function from the Kernel API Manual, and honestly? it does exactly one thing and it does it iconically: it flushes a specific page of a vma. that's the whole vibe. no cap.

✨ NAME ✨

octeon_flush_cache_page — flush a specific page of a vma 🫶

🌸 SYNOPSIS 🌸

void octeon_flush_cache_page (struct vm_area_struct *vma , unsigned long
       page , unsigned long pfn );

heads up bestie, the return type is void — it gives nothing back, it just does the thing. main character energy fr fr 💅

🎀 ARGUMENTS 🎀

• vma — the VMA you want the page flushed for. this is your *struct vm_area_struct *` pointer, she's the context, she's the moment. literally the "for whom" of the whole operation.
• page — the page to flush, an unsigned long. this is THE page. the one. the target. 🎯
• pfn — the page frame number, also unsigned long. the frame number of the page, bestie. say it with me: page frame number. 🦋
