Subject: tests: add dmesg -d -t and -t -d timestamp format tests
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=588d2be090127355021dad23bf2a635c340e68d7;p=thirdparty%2Futil-linux.git

tests: add dmesg -d -t and -t -d timestamp format tests

Add two sub-tests to verify that -d -t (delta-notime) and -t -d
(notime-delta) both produce delta-only output regardless of option
order.
