rbd: acquire header_rwsem just once in rbd_queue_workfn() Currently header_rwsem is acquired twice: once in rbd_dev_parent_get() when the image request is being created and then in rbd_queue_workfn() to capture mapping_size and snapc. Introduce rbd_img_capture_header() and move image request allocation so that header_rwsem can be acquired just once. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
