Merge tag 'ceph-for-7.0-rc1' of https://github.com/ceph/ceph-client

Pull ceph updates from Ilya Dryomov:
 "This adds support for the upcoming aes256k key type in CephX that is
  based on Kerberos 5 and brings a bunch of assorted CephFS fixes from
  Ethan and Sam. One of Sam's patches in particular undoes a change in
  the fscrypt area that had an inadvertent side effect of making CephFS
  behave as if mounted with wsize=4096 and leading to the corresponding
  degradation in performance, especially for sequential writes"
