    smb3: query attributes on file close · 43f8a6a7
    Steve French authored
    Since timestamps on files on most servers can be updated at
    close, and since timestamps on our dentries default to one
    second we can have stale timestamps in some common cases
    (e.g. open, write, close, stat, wait one second, stat - will
    show different mtime for the first and second stat).
    
    The SMB2/SMB3 protocol allows querying timestamps at close
    so add the code to request timestamp and attr information
    (which is cheap for the server to provide) to be returned
    when a file is closed (it is not needed for the many
    paths that call SMB2_close that are from compounded
    query infos and close nor is it needed for some of
    the cases where a directory close immediately follows a
    directory open.
