svn commit: r210337 - head/sys/kern

[Attilio Rao]

New Revision: 210337
URL: http://svn.freebsd.org/changeset/base/210337

Log:
  Probabilly defaulting to KTR_GEN is not the right decision when KTR_MASK
  is not defined at all because KTR_GEN is still a valid class and some
  traces may fit in. Default to 0, instead, and block any tracing.
  
  As long as this is a POLA violation (some thirdy-part code, even if
  that may be a questionable choice, could be rely on that feature) a
  MFC possibility might be carefully evaluated.
