 def getattr(self, path, fh):
 """Called by FUSE when the attributes for a file or directory are required. Returns a dictionary with keys identical to the stat C structure of stat(2). st_atime, st_mtime and st_ctime should be floats. On OSX, st_nlink should count all files inside the directory. On Linux, only the subdirectories are counted. The 'st_dev' and 'st_blksize' fields are ignored. The 'st_ino' field is ignored except if the 'use_ino' mount option is given. This method gets very heavy traffic. """
