In this case, I believe that it should return directly? If it can't
enter in the
unsafe region the output buffer is not reliable anymore, so
retrying the send
the buffer to a different target isn't correct anymore. Petr, John,
do you
agree?

That makes sense. I undersatnd that the ownership will not be
re-acquired here by just looping through the netconsole targets,
right?

Yes, take a look into the drivers/tty/serial/*, some of the only
reacquire the context to reset some hardware registers, since the
printing context was lost. In this case, for you, I don't believe that
you can't continue trying to send data to other targets, since the
original data is gone.

In any case, the context reacquire method is nbcon_reacquire_nobuf.
