vmw_bo_dirty_scan_mkwrite(9)

🌸 NAME 🌸

vmw_bo_dirty_scan_mkwrite(9) — reset the mkwrite dirty-tracking method. This one's straight out of the Kernel API Manual, bestie, and it's lowkey the little reset moment for the mkwrite tracking vibe 💅✨

✨ SYNOPSIS ✨

void vmw_bo_dirty_scan_mkwrite (struct vmw_bo *vbo );

That's the whole signature, no cap 🫶

🫶 ARGUMENTS 🫶

• vbo — the buffer object to scan 🦋

💅 DESCRIPTION 💅

Okay so here's the tea: this function write-protects pages written to, so that consecutive write accesses will trigger a call to mkwrite 🌸

And yes — this function may change the dirty-tracking method 😭 so don't act surprised if the tracking method switches up on you.
