  Benefits of the solution:
  Avoid mount failure when there are more than 8192 inode spaces.
  
  Work Around:
  None
  
  Problem trigger:
  The sanity check for the number of inode spaces created in a
  file systemwas using the plain maxInodeSpaces configured in the
  file system. It is wrong becauseinternally, with the use of
  inodeSpaceMask, the maximum number of inode spacesin a file
  system should be the next power of 2 number of maxInodeSpaces.
  
  Symptom:
  Unable to mount the file system.
