If this patch causes issues outside of the trigger phase, then maybe we could just change the BE nonatomic flag temporarily and restore it after taking the lock, but IMHO something else is broken in other drivers.
Now that I think of it, this wouldn't work, the type of locks for the BEs has to be set before the trigger: the DPCM flow is that we start from the FEs and find which BEs need to be triggered. That would prevent us from modifying a global BE property - each FE is independent.
