While testing an ath10k firmware that often crashed under load,
I was seeing kernel crashes as well. One of them appeared to
be a dereference of a NULL flow object in fq_tin_dequeue.
I have since fixed the firmware flaw, but I think it would be
worth adding the WARN_ON in case

This was originally mistakenly submitted to net-next. Resubmitting to net.
The comparison of numvecs < 0 is always false because numvecs is a u32

fchownat() doesn't even hold refcnt of fd until it figures out
fd is really needed (otherwise is ignored) and releases it after
it resolves the path. This means sock_close() could race with

I have since fixed the firmware flaw, but I think it would be
