Yan, Zheng f275635ee0 ceph: wait on writeback after writing snapshot data ... In sync mode, writepages() needs to write all dirty pages. But it can only write dirty pages associated with the oldest snapc. To write dirty pages associated with next snapc, it needs to wait until current writes complete. Without this wait, writepages() keeps looking up dirty pages, but the found dirty pages are not writeable. It wastes CPU time.
