   Why? It will make supporting netconsole easier which has to be careful
   to never recurse in the network driver.

printk can check this

Actually it already does, to cover the case where an interrupt handler calls
printk while process-context code is performing a printk.

The nested printk will squirt the message into the log buffer and the
"outer" code will display it.
