ceph: scattered page writeback This patch makes ceph_writepages_start() try using single OSD request to write all dirty pages within a strip unit. When a nonconsecutive dirty page is found, ceph_writepages_start() tries starting a new write operation to existing OSD request. If it succeeds, it uses the new operation to writeback the dirty page.
