Must xQueueSendFromISR wake a task?

In V5.0.2, what would happen if I ignored the fact that a higher priority task were woken by xQueueSendFromISR?

The reason I ask is that I’m logging errors, which can occur during an ISR. The error logging routine then detects that it’s in an ISR and calls xQueueSendFromISR rather than xQueueSend(). I don’t have any (good) way to return the task woken status back to the ISR, and there’s no way to handle the task switch upon return from the logging function - which I probably wouldn’t want to do anyway, since it’s supposed to return to the ISR.

I believe the only “problem” you will run into is that the higher priority task won’t run until something runs the scheduler again (at most till the next clock tick).
