    smb3: allow more detailed protocol info on open files for debugging · dfe33f9a
    Steve French authored
    In order to debug complex problems it is often helpful to
    have detailed information on the client and server view
    of the open file information.  Add the ability for root to
    view the list of smb3 open files and dump the persistent
    handle and other info so that it can be more easily
    correlated with server logs.
    
    Sample output from "cat /proc/fs/cifs/open_files"
