I tested these patches. Only thing I found are these sparse
warnings:

net/netlink/af_netlink.c:2893:12: warning: context imbalance in 'netlink_walk_start' - different lock contexts for basic block
net/netlink/af_netlink.c:2907:13: warning: context imbalance in 'netlink_walk_stop' - unexpected unlock
