Juliet Kim b27507bb59 net/ibmvnic: unlock rtnl_lock in reset so linkwatch_event can run ... Commit a5681e20b5 ("net/ibmnvic: Fix deadlock problem in reset") made the change to hold the RTNL lock during a reset to avoid deadlock but linkwatch_event is fired during the reset and needs the RTNL lock. That keeps linkwatch_event process from proceeding until the reset is complete. The reset process cannot tolerate the linkwatch_event processing after reset completes, so release the RTNL lock during the process to allow a chance for linkwatch_event to run during reset. This does not guarantee that the linkwatch_event will be processed as soon as link state changes, but is an improvement over the current code where linkwatch_event processing is always delayed, which prevents transmissions on the device from being deactivated leading transmit watchdog timer to time-out. Release the RTNL lock before link state change and re-acquire after the link state change to allow linkwatch_event to grab the RTNL lock and run during the reset.
