* 'block-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/block: [PATCH] fix rmmod problems with elevator attributes, clean them up [PATCH] elevator_t lifetime rules and sysfs fixes [PATCH] noise removal: cfq-iosched.c [PATCH] don't bother with refcounting for cfq_data [PATCH] fix sysfs interaction and lifetime rules handling for queues [PATCH] regularize blk_cleanup_queue() use [PATCH] fix cfq_get_queue()/ioprio_set(2) races [PATCH] deal with rmmod/put_io_context() races [PATCH] stop elv_unregister() from rogering other iosched's data, fix locking [PATCH] stop cfq from pinning queue down [PATCH] make cfq_exit_queue() prune the cfq_io_context for that queue [PATCH] fix the exclusion for ioprio_set() [PATCH] keep sync and async cfq_queue separate [PATCH] switch to use of ->key to get cfq_data by cfq_io_context [PATCH] stop leaking cfq_data in cfq_set_request() [PATCH] fix cfq hash lookups [PATCH] fix locking in queue_requests_store() [PATCH] fix double-free in blk_init_queue_node() [PATCH] don't do exit_io_context() until we know we won't be doing any IO
