mei_cl_flush_queues(9)

🦋 NAME 🦋

okay so bestie, welcome to the Kernel API Manual (section 9, kernel dev vibes only ✨) — this page is all about mei_cl_flush_queues, and it literally flushes queue lists belonging to cl. that's it. that's the whole personality. 💅

---

🌸 SYNOPSIS 🌸

int mei_cl_flush_queues (struct mei_cl *cl , const struct file *fp );

it's giving "small function, big cleanup energy" 🧹✨

---

🎀 ARGUMENTS 🎀

• cl — the host client 💖 like, the actual client you're doing all this for.
• fp — a file pointer (the one matching the cb file object, iykyk). and guess what — it may be NULL. yes bestie, NULL is allowed here, we're not gatekeeping 🙈

---

👑 RETURN 👑

• 0 on success — slay, the flush worked, nothing left behind ✨
• -EINVAL if cl or cl->dev is NULL — like, if you hand it nothing, it's gonna be real clear about it 💀

lowkey a reminder: fp can be NULL and that's fine, but cl and cl->dev better not be, or you're getting that -EINVAL straight to the face 😭
