The commit 41b14fb8724d ("net: Do not clear the sock TX queue in sk_set_socket()") removes sk_tx_queue_clear() from sk_set_socket() and adds it instead in sk_alloc() and sk_clone_lock() to fix an issue introduced in the commit e022f0b4a03f ("net: Introduce sk_tx_queue_mapping"). However, the original commit had already put sk_tx_queue_clear() in sk_prot_alloc(): the callee of sk_alloc() and sk_clone_lock(). Thus sk_tx_queue_clear() is called twice in each path currently.
This patch removes the redundant calls of sk_tx_queue_clear() in sk_alloc() and sk_clone_lock().
