ceph-for-6.10-rc1

We have a series from Xiubo that adds support for additional access
checks based on MDS auth caps which were recently made available to
clients.  This is needed to prevent scenarios where the MDS quietly
discards updates that a UID-restricted client previously (wrongfully)
acked to the user.  Other than that, just a documentation fixup.
