UCT mentions commits 9060cb719e61b685ec0102574e10337fa5f445ea (specific
to AF_ALG) and ff7b11aa481f682e0e9711abfeb7d03f5cd612bf (all sockets).
The other commit we should care about is
6d8c50dcb029872b298eea68cc6209c866fd3e14 ("socket: close race condition
between sock_close() and sockfs_setattr()").
If you have that one, you should expect ENOENT (which is what the test
case expects), but only if sock_close wins the race. If it doesn't, you
might still succeed at sockfs_setattr, and then we get this test
failure.
