Our general preference is to zap code.

/me stares at:

$ git diff --stat -M v2.6.30..v2.6.31-rc1 | tail -1
7743 files changed, 782278 insertions(+), 403162 deletions(-)

/me corrects himself:

Okay, so the zapping of code is the divine guiding principle we've
been following for 15 years. Ending up with a kernel that is 11
million lines of code is a small imperfection of mankind and is to
be fixed.
