net: fix sleeping for sk_wait_event()
Similar to commit 14135f30e33c ("inet: fix sleeping inside inet_wait_for_connect()"), sk_wait_event() needs to fix too, because release_sock() is blocking, it changes the process state back to running after sleep, which breaks the previous prepare_to_wait(). Switch to the new wait API. Cc: Eric Dumazet <eric.dumazet@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.
