🌸 NAME 🌸

_cifsFileInfo_put — release a reference of file priv data. that's it, that's the vibe. 💅

---

✨ SYNOPSIS ✨

       void _cifsFileInfo_put (struct cifsFileInfo *cifs_file , bool
       wait_oplock_handler , bool offload );

---

🎀 ARGUMENTS 🎀

• cifs_file — cifs/smb3 specific info (eg refcounts) for an open file. 🦋
• wait_oplock_handler — must be false if called from oplock_break_handler. like, genuinely must be false, bestie. 🚨
• offload — not offloaded on close and oplock breaks. 💀

---

🔥 DESCRIPTION 🔥

okay so real talk: this may involve closing the filehandle cifs_file out on the server. 📡

🚨 Must be called without holding tcon->open_file_lock, cinode->open_file_lock and cifs_file->file_info_lock. like, do not be holding those locks. periodt. 💅

If wait_for_oplock_handler is true and we are releasing the last reference, wait for any running oplock break handler of the file and cancel any pending one. ⏳ iconic behavior, honestly.
