kmsan_handle_urb(9)

💖 NAME 💖

okay so bestie, welcome to the kmsan_handle_urb(9) page from the Kernel API Manual — it's literally about how to Handle a USB data transfer. slay.

✨ SYNOPSIS ✨

void kmsan_handle_urb (const struct urb *urb , bool is_out );

🎀 ARGUMENTS 🎀

• urb — a struct urb pointer. yep, the USB request block itself, bestie 🫶
• is_out — data transfer direction; true means output to hardware. iconic little bool ✨

🦋 DESCRIPTION 🦋

okay so here's the tea: if is_out is true, KMSAN checks the transfer buffer of urb. Otherwise, KMSAN initializes the transfer buffer. that's the whole vibe, no cap 💅
