Kubuntu CI performs QA on whether all patches that are under version control are also listed in the debian/patches/series file. Sometimes it can be desired that a patch gets disabled but not removed (e.g. debian patch) making it necessary to ignore warnings about missing patches.
Ignore rules are placed next to the series file in debian/patches/ and named ignore.
The ignore file has exactly the same format as the series itself. Each line contains one patch name that should be ignored. Lines starting with a hash character are comments. Empty lines are ignored.
$ cat debian/patches/ignore # Debian specific defaults, we have our own patch for ours. debianize_akregator_default.diff
