Subject: Support OP_NOMATCH for TAG key
X-Git-Tag: v227~38^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4302857b31a8e89ddeba0921fee06a1ff0237996;p=thirdparty%2Fsystemd.git

Support OP_NOMATCH for TAG key

The TAG key can be used in rules for event matching. At the moment, it
does not support inequality tests. This patch enhances the key test to
validate the rule if it does not contain a given TAG (by TAG!="value").
