    userns: Implement struct kqid · e8a3e471
    Eric W. Biederman authored
    Add the data type struct kqid which holds the kernel internal form of
    the owning identifier of a quota.  struct kqid is a replacement for
    the implicit union of uid, gid and project id stored in an unsigned
    int and the quota type field that is was used in the quota data
    structures.  Making the data type explicit allows the kuid_t and
    kgid_t type safety to propogate more thoroughly through the code,
    revealing more places where uid/gid conversions need be made.
    Along with the data type struct kqid comes the helper functions
    qid_eq, qid_lt, from_kqid, from_kqid_munged, qid_valid, make_kqid,
    make_kqid_invalid, make_kqid_uid, make_kqid_gid.
