Kuniyuki Iwashima	625a8bb556	af_unix: Do not use atomic ops for unix_sk(sk)->inflight. ... [ Upstream commit 97af84a6bba2ab2b9c704c08e67de3b5ea551bb2 ] When touching unix_sk(sk)->inflight, we are always under spin_lock(&unix_gc_lock). Let's convert unix_sk(sk)->inflight to the normal unsigned long.

Kuniyuki Iwashima	c92f3be292	af_unix: Annotate data-race of gc_in_progress in wait_for_unix_gc(). ... [ Upstream commit 31e03207119a535d0b0e3b3a7f91983aeb2cb14d ] gc_in_progress is changed under spin_lock(&unix_gc_lock), but wait_for_unix_gc() reads it locklessly. Let's use READ_ONCE().
