If anyone has any objections, please let me know. ------------------ From: Alex Elder (cherry picked from commit 8f43fb53894079bf0caab6e348ceaffe7adc651a) Rather than passing a bunch of arguments to be filled in with the content of the ceph_auth_handshake buffer now returned by the get_authorizer method, just use the returned information in the caller, and drop the unnecessary arguments.
