что за ошибки? не на структуры времени

пойду код поправлю

и еще раз попробую

погоди, щас кину правленный

попробуй этот, там и под 5 ядро уже фиксы есть.

на гитхабе что то нашел

но тоже не собирается

там те же фиксы практически, setup_timer заменен на timer_setup, но я не делал проверки на версии ядра, т.к. мне надо было под 5.1

попробуй мой код, я правда под 4.19 не собирал
