add_taint (9)

void add_taint(unsigned flag, enum lockdep_ok lockdep_ok);

flag

one of the TAINT_* constants.

lockdep_ok

whether lock debugging is still OK.

If something bad has gone wrong, you'll want lockdebug_ok = false, but for some notewortht-but-not-corrupting cases, it can be set to true.
