+ *
+ * 1. smbd-1 opens the file and sets the oplock
+ * 2. smbd-2 tries to open the file. open() fails(EAGAIN) and open is deferred.
+ * 3. smbd-1 sends oplock break request to the client.
+ * 4. smbd-1 closes the file.
+ * 5. smbd-1 opens the file and sets the oplock.
+ * 6. smbd-2 calls defer_open_done(), and should re-break the oplock.
