💅 __genwqe_purge_ddcb — NAME

okay so welcome to the Kernel API Manual, bestie — this is __genwqe_purge_ddcb(9), and what it does is Remove a DDCB from the workqueue ✨ no cap, that's literally it.

📜 SYNOPSIS

int __genwqe_purge_ddcb (struct genwqe_dev *cd , struct ddcb_requ *req
);

like, it hands you back an int, and it takes those two things up there 👆 that's the whole signature, periodt.

🧸 ARGUMENTS

  • ​cd — the genwqe device descriptor 🫶 (your cute little handle to the device, iykyk)
  • req — the DDCB request 💌 the one we're purging, the main character of this whole function

🔥 DESCRIPTION

okay so here's the tea 🍵 — this will fail when the request was already FETCHED. and in that case? you literally cannot just yank it, you need to wait until it is finished. no shortcuts, bestie 😭. else — meaning if it wasn't already FETCHED — the DDCB can be reused, slay 💅.

this function also ensures that the request data structure is removed from ddcb_req[] ✨ so like, the cleanup is baked in, iconic behaviour honestly.

💀 do not forget to call this function when genwqe_wait_ddcb fails, such that the request gets really removed from ddcb_req[]. like fr fr, don't leave it floating in there, that's not the vibe.

🎀 RETURN

  • 0 — success 🌸 that's it, that's the return value
