This was tracked down from https://syzkaller.appspot.com/bug?extid=5f1acda7e06a2298fae6,
and unfortunately it doesn't fix an actual leak of 'struct fasync_struct' objects. I'm
suspecting an undefined behavior caused by the race condition somewhere around socket
impersonation tricks in 'smc_switch_to_fallback()', and it would be very helpful if an
original authors can take a look as well.
