Subject[PATCH review 04/85] ceph: Convert struct ceph_mds_request to use kuid_t and kgid_t
From: "Eric W. Biederman" <ebiederm@xmission.com>

Hold the uid and gid for a pending ceph mds request using the types
kuid_t and kgid_t. When a request message is finally created convert
the kuid_t and kgid_t values into uids and gids in the initial user
namespace.
