block: add a disk_uevent helper
Add a helper to call kobject_uevent for the disk and all partitions, and unexport the disk_part_iter_* helpers that are now only used in the core block code. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
