This kernel version doesn't have aio poll, but the fix for POLLFREE with
exclusive waiters is still applicable to it.  This series resolves
conflicts in all three patches, mostly due to POLLHUP having been
renamed to EPOLLHUP in more recent kernels.

Eric Biggers (3):
  wait: add wake_up_pollfree()
  binder: use wake_up_pollfree()
  signalfd: use wake_up_pollfree()

Sorry, ignore this one; there's a build error in kernel/sched/wait.c.
