ceph: improving efficiency of syncfs (2018-01-30 21:10:15 +0100)

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

On the CephFS side we have a large number of cap handling improvements,
a fix for our long-standing abuse of ->journal_info in ceph_readpages()
and yet another dentry pointer management patch.

----------------------------------------------------------------

libceph: check kstrndup() return value

rbd: obj_request->completion is unused

rbd: don't NULL out ->obj_request in rbd_img_obj_parent_read_full()
rbd: whitelist RBD_FEATURE_OPERATIONS feature bit
