  Modified files:
    sys/ufs/ffs          ffs_balloc.c ffs_vfsops.c 
    sys/ufs/ufs          inode.h ufs_inode.c 
  Log:
  Eliminate the i_devvp field from the incore UFS inodes, we can
  get the same value from ip->i_ump->um_devvp.
  
  This saves a pointer in the memory copies of inodes, which can
  easily run into several hundred kilobytes.
  
  The extra indirection is unmeasurable in benchmarks.
