  *    in case there are ufs implementations that have strange bytesexes,
  *    you'll need to modify code here as well as in ufs_super.c and ufs_fs.h
  *    to support them.
- *
- *    WE ALSO ASSUME A REMOTELY SANE ARCHITECTURE BYTESEX.
- *    We are not ready to confront insane bytesexual perversions where
- *    conversion to/from little/big-endian is not an involution.
- *    That is, we require that XeYZ_to_cpu(x) == cpu_to_XeYZ(x)
- *
- *    NOTE that swab macros depend on a variable (or macro) swab being in
- *    scope and properly initialized (usually from sb->u.ufs_sb.s_swab).
- *    Its meaning depends on whether the architecture is sane-endian or not.
- *    For sane architectures, it's a flag taking values UFS_NATIVE_ENDIAN (0)
- *    or UFS_SWABBED_ENDIAN (1), indicating whether to swab or not.
- *    For pervert architectures, it's either UFS_LITTLE_ENDIAN or
- *    UFS_BIG_ENDIAN whose meaning you'll have to guess.
- *
- *    It is important to keep these conventions in synch with ufs_fs.h
- *    and super.c. Failure to do so (initializing swab to 0 both for
- *    NATIVE_ENDIAN and LITTLE_ENDIAN) led to nasty crashes on big endian
- *    machines reading little endian UFSes. Search for "swab =" in super.c.
- *
- *    I also suspect the whole UFS code to trust the on-disk structures
- *    much too much, which might lead to losing badly when mounting
- *    inconsistent partitions as UFS filesystems. fsck required (but of
- *    course, no fsck.ufs has yet to be ported from BSD to Linux as of 199808).
