Subject: [PATCH net] hv_netvsc: Fix extra rcu_read_unlock in netvsc_recv_callback()
Date: Fri, 19 Jul 2019 17:33:51 +0000 [thread overview]
Message-ID: <1563557581-17669-1-git-send-email-haiyangz@microsoft.com> (raw)
There is an extra rcu_read_unlock left in netvsc_recv_callback(),
after a previous patch that removes RCU from this function.
This patch removes the extra RCU unlock.
Fixes: 345ac08990b8 ("hv_netvsc: pass netvsc_device to receive callback")
