Back many years ago, the owner field was used to email the test owner when auto-qa failed that test. It is not needed anymore - if you want to know who wrote the test, look it up in git.... Script used was: $ sed -i -e "/^# creator/d" -e "/^owner/d" [0-3][0-9][0-9] Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Phil White <pwhite@sgi.com> [rjohnston@sgi.com added TOT changes] Signed-off-by: Rich Johnston <rjohnston@sgi.com>
