  14                 UMSDOS manage special file and fifo as normal empty
  15                 msdos file. fifo inode processing conflict with msdos
  16                 processing. So I insert the pipe_inode_info so the
  17                 information does not overlap. This increases the size of
  18                 the msdos_inode_info, but the clear winner here is
  19                 the ext2_inode_info. So it does not change anything to
  20                 the total size of a struct inode.

  22                 I have not put it conditional. With the advent of loadable
  23                 file system drivers, it would be very easy to compile
  24                 a MsDOS FS driver unaware of UMSDOS and then later to
  25                 load a (then incompatible) UMSDOS FS driver.
