net/smc: use GFP_ATOMIC allocation in smc_pnet_add_eth()
My last patch moved the netdev_tracker_alloc() call to a section protected by a write_lock(). I should have replaced GFP_KERNEL with GFP_ATOMIC to avoid the infamous: BUG: sleeping function called from invalid context at include/linux/sched/mm.h:256 Fixes: 28f922213886 ("net/smc: fix ref_tracker issue in smc_pnet_add()") Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
