This patchset consists of several parts. Patches [1-2] optimize likely case of request_end(), and make this function to take fiq->waitq.lock only, when it is really needed. This improves performance of this function completes.
Patch 3 makes request_end() to call wake_up() only for not background requests (background requests never wait answer), and this optimizes this function a bit more
Patches [4-6] makes code to check userspace requests correct interrupt id to requeue (whether we've sent this interrupt).

Kirill Tkhai (6): fuse: Kill fasync only if interrupt is queued in queue_interrupt() fuse: Optimize request_end() by not taking fiq->waitq.lock fuse: Wake up req->waitq of only not background requests in request_end() fuse: Check for FR_SENT bit in fuse_dev_do_write() fuse: Do some refactoring in fuse_dev_do_write() fuse: Verify userspace asks to requeue interrupt that we really sent
