Subject: predict: fully deactivate prediction with `period = 0`
X-Git-Tag: v5.6.0~3^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=89b41a7af878be720fa0f19f70051eb6232a068b;p=thirdparty%2Fknot-resolver.git

predict: fully deactivate prediction with `period = 0`

That setting is recommended by documentation but it would still leave
the timer triggering repeatedly.  Maybe it didn't cause any practical
difference, but it was unnecessary and possibly confusing.
