pollution. Specifically: ROOTINO -> UFS_ROOTINO WINO -> UFS_WINO NXADDR -> UFS_NXADDR NDADDR -> UFS_NDADDR NIADDR -> UFS_NIADDR MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency) Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have the same values in ext2fs and ffs. No functional change intended.
