Jia-Ju Bai 343eba69c6 net: tipc: Fix a sleep-in-atomic bug in tipc_msg_reverse ... The kernel may sleep under a rcu read lock in tipc_msg_reverse, and the function call path is: tipc_l2_rcv_msg (acquire the lock by rcu_read_lock) tipc_rcv tipc_sk_rcv tipc_msg_reverse pskb_expand_head(GFP_KERNEL) --> may sleep tipc_node_broadcast tipc_node_xmit_skb tipc_node_xmit tipc_sk_rcv tipc_msg_reverse pskb_expand_head(GFP_KERNEL) --> may sleep To fix it, "GFP_KERNEL" is replaced with "GFP_ATOMIC".
