New Revision: 293444
URL: https://svnweb.freebsd.org/changeset/base/293444

Log:
  - Move functions that might be used in class-specific cleanup functions
    (geom_test_cleanup, etc) down so the testcases don't emit noise when
    bailing
  - Conform to the TAP protocol better when dealing with classes that can't
    be loaded and with temporary files that can't be allocated for tracking
    md(4) devices.
