Так как подсистема n_tracerouter давно не поддерживается в коде ядра,
то она стала неиспользуемой и не пригодной к использованию. 

Во время фаззинга находятся ряд срабатываний, к примеру 'possible deadlock',
которые возникают из-за конфликтов устаревшего n_tracerouter с другими подсистемами
ядра.

Учитывая, что в upstream, начиная с ядра 5.12 (1), было принято отказаться от данного
модуля (4), предлагаю последовать примеру upstream, и отключить в нашем ядре:
* std-def P10       (5.10)
* std-def c9f2      (5.10)

Disable n_tracerouter in the config because of it's unsupported, unused and obsolete.
It occurs different false positive errors during kernel's fuzzing, for example:
various 'possible deadlocks'.

It has already been removed from upstream in the commit bacc2a4ee89f [1].

Applied, thanks.

Это не стандартный формат для отключения опции, но он сработал. В будущем
лучше слать в общепринятом формате.

Спасибо,
