🎀 SYNOPSIS 🎀

int genwqe_ddcbs_in_flight (struct genwqe_dev *cd );

like, that's the whole vibe. one function, one argument, it's giving "small but important" ✨

💖 ARGUMENTS 💖

• cd — pointer to the genwqe device descriptor 🫶 that's it, that's the whole argument list, she's a simple girl

🌈 DESCRIPTION 🌈

so what this does is keep track of the number of DDCBs that are currently in the queue 👑

this count is needed for statistics, and also for the condition where we want to wait — or, honestly, better to do polling in case there are no interrupts available 😭 like when the interrupts just aren't showing up, you gotta know how many DDCBs are sitting in the queue so you can decide what to do. fr fr.
