Pull aio poll fixes from Eric Biggers: "Fix three bugs in aio poll, and one issue with POLLFREE more broadly: - aio poll didn't handle POLLFREE, causing a use-after-free. - aio poll could block while the file is ready. - aio poll called eventfd_signal() when it isn't allowed. - POLLFREE didn't handle multiple exclusive waiters correctly. This has been tested with the libaio test suite, as well as with test programs I wrote that reproduce the first two bugs. I am sending this pull request myself as no one seems to be maintaining this code" * tag 'aio-poll-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: aio: Fix incorrect usage of eventfd_signal_allowed() aio: fix use-after-free due to missing POLLFREE handling aio: keep poll requests on waitqueue until completed signalfd: use wake_up_pollfree() binder: use wake_up_pollfree() wait: add wake_up_pollfree()
