Jeff Layton 785892fe88 ceph: cache layout in parent dir on first sync create ... If a create is done, then typically we'll end up writing to the file soon afterward. We don't want to wait for the reply before doing that when doing an async create, so that means we need the layout for the new file before we've gotten the response from the MDS. All files created in a directory will initially inherit the same layout, so copy off the requisite info from the first synchronous create in the directory, and save it in a new i_cached_layout field. Zero out the layout when we lose Dc caps in the dir.
