From: Ido Schimmel <idosch@mellanox.com> Date: Mon, 18 Jan 2016 17:30:22 +0200 > We can't be within an RCU read-side critical section when deleting > VLANs, as underlying drivers might sleep during the hardware operation. > Therefore, replace the RCU critical section with a mutex. This is > consistent with team_vlan_rx_add_vid. > > Fixes: 3d249d4ca7d0 ("net: introduce ethernet teaming device") > Acked-by: Jiri Pirko <jiri@mellanox.com> > Signed-off-by: Ido Schimmel <idosch@mellanox.com> Applied and queued up for -stable, thanks.
