Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse
Pull fuse updates from Miklos Szeredi: "This contains two patchsets from Maxim Patlasov. The first reworks the request throttling so that only async requests are throttled. Wakeup of waiting async requests is also optimized. The second series adds support for async processing of direct IO which optimizes direct IO and enables the use of the AIO userspace interface." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse: fuse: add flag to turn on async direct IO fuse: truncate file if async dio failed fuse: optimize short direct reads fuse: enable asynchronous processing direct IO fuse: make fuse_direct_io() aware about AIO fuse: add support of async IO fuse: move fuse_release_user_pages() up fuse: optimize wake_up fuse: implement exclusive wakeup for blocked_waitq fuse: skip blocking on allocations of synchronous requests fuse: add flag fc->initialized fuse: make request allocations for background processing explicit
