drop_monitor: Add error code to detect duplicate state changes
Patch to add -EAGAIN error to dropwatch netlink message handling code. -EAGAIN will be returned anytime userspace attempts to transition the state of the drop monitor service to a state that its already in. That allows user space to detect this condition, so it doesn't wait for a success ACK that will never arrive. Tested successfully by me Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
