Eric Biggers a880b28a71 binder: use wake_up_pollfree() ... wake_up_poll() uses nr_exclusive=1, so it's not guaranteed to wake up all exclusive waiters. Yet, POLLFREE *must* wake up all waiters. epoll and aio poll are fortunately not affected by this, but it's very fragile. Thus, the new function wake_up_pollfree() has been introduced. Convert binder to use wake_up_pollfree(). Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Fixes: f5cb779ba1 ("ANDROID: binder: remove waitqueue when thread exits.")
