✨ NAME ✨

cifs_queue_oplock_break — queue the oplock break handler for cfile 🦋

---

🌸 SYNOPSIS 🌸

void cifs_queue_oplock_break (struct cifsFileInfo *cfile );

that's it. that's the whole signature. no return value, it's giving void and unbothered 💅

---

🎀 ARGUMENTS 🎀

• cfile — the file you wanna break the oplock on, periodt. that's the whole vibe 🫶

---

🔥 DESCRIPTION 🔥

so here's the tea ☕ — this function gets called from the demultiplex thread when it receives an oplock break for cfile. like, the thread rolls up, sees an oplock break, and goes "not me handling this, let me queue it" 😭

and now the part where you gotta pay attention, bestie, because there are assumptions and they are not optional 👀

Assumes tcon->open_file_lock is held. Assumes cfile->file_info_lock is NOT held.

read that twice. one lock held, the other one absolutely not held. it's giving "vibe check before you call this" 💀 get it wrong and that's on you, fr fr.
