2012-09-18userns: Implement struct kqidEric W. Biederman1-0/+132
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.
