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.
