проблему решил. все изза того что с версии ядра 5.15.0 некоторые вещи уже реализуются по другому

Но нужно собрать под Fedora34 (35) Исходники одинаковы совершенно. 1. В чем причина появления ошибок? Не соответствующий h идер? строгости более позднего компилятора? Отсутствие каких-то вещей в более поздней версии ядра? 2. Как поправить и решить сборку более правильно?
