Things have been very quiet on the rbd side, as work continues on the
big ticket items slated for the next merge window.

a fix for our long-standing abuse of ->journal_info in ceph_readpages()
and yet another dentry pointer management patch.

->sync_fs is for guaranteeing flush completion for all inodes at that point.
