Using a fairly lame grep, there are 10k instances versus 60k for u64 and
friends.  Sustract about 2.5k used in include/ and possibly part of
userspace interfaces, that leaves about 7.5k.

joern@...way:/usr/src/kernel/logfs$ sgrep '\<u[136][246]\>' .|wc
  60306  313780 3960665
joern@...way:/usr/src/kernel/logfs$ sgrep '\<__[lb]e[136][246]\>' .|wc
  10013   52235  635047
joern@...way:/usr/src/kernel/logfs$ sgrep '\<__[lb]e[136][246]\>' include|wc
   2624   15100  173176

Actually going through them all, the overwhelming majority is used for
structures.  I seem to be quite the oddball indeed.

Will change.
