-Subject: [PATCH] wireguard: socket: remove extra call to synchronize_net
-
-commit 1fbc33b0a7feb6ca72bf7dc8a05d81485ee8ee2e upstream.
-
-synchronize_net() is a wrapper around synchronize_rcu(), so there's no
-point in having synchronize_net and synchronize_rcu back to back,
-despite the documentation comment suggesting maybe it's somewhat useful,
-"Wait for packets currently being received to be done." This commit
-removes the extra call.
