Hello.

есть модуль для специализированной железки для рассчетов.
этот модуль прекрасно собирается и работает на ядрах < 2.6.25
на ядрах >= 2.6.25 при компиляции получаем:

error: variable 'fops' has initializer but incomplete type

Что за нововведения произошли в более новых ядрах?
Куда смотреть и что починить?
От версии компилятора это не зависит.

Thanx.
