Subject[for-next][PATCH 4/8] ktest.pl: Add a NOT operator
From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

There is a NOT DEFINED operator, but there is not an operator that can
negate any other expression.

For example: NOT (${FOO} == boot || ${BAR} == run)

Add the keyword NOT to allow the ktest.pl config files to negate operators.
