decnet: convert dndev_lock to spinlock There is no reason for this lock to be reader/writer since the reader only has lock held for a very brief period. The overhead of read_lock is more expensive than spinlock. Compile tested only, I am not a decnet user. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.
