Subject: [Intel-wired-lan] [PATCH net-next 2/3] udp_tunnel: remove rtnl_lock dependency
Date: Tue, 20 May 2025 13:36:13 -0700 [thread overview]
Message-ID: <20250520203614.2693870-3-stfomichev@gmail.com> (raw)
In-Reply-To: <20250520203614.2693870-1-stfomichev@gmail.com>
Drivers that are using ops lock and don't depend on RTNL lock
still need to manage it because udp_tunnel's RTNL dependency.
Introduce new udp_tunnel_nic_lock and use it instead of
rtnl_lock. Drop non-UDP_TUNNEL_NIC_INFO_MAY_SLEEP mode from
udp_tunnel infra (udp_tunnel_nic_device_sync_work needs to
grab udp_tunnel_nic_lock mutex and might sleep).
