Convert nfs_map_name_to_uid to return a kuid_t value. Convert nfs_map_name_to_gid to return a kgid_t value. Convert nfs_map_uid_to_name to take a kuid_t paramater. Convert nfs_map_gid_to_name to take a kgid_t paramater. Tweak nfs_fattr_map_owner_to_name to use a kuid_t intermediate value. Tweak nfs_fattr_map_group_to_name to use a kgid_t intermediate value. Which makes these functions properly handle kuids and kgids, including erroring of the generated kuid or kgid is invalid. Cc: "J.
