Rename struct xlat to struct xlat_data and make struct xlat an xlat descriptor that contains various information about xlat. So far, it's type and number of items. As a result, xlookup/printxval now have enought information for handling xlat depending on its type, so no *index/*_search APIs are needed. * xlat.h (struct xlat_data): Rename from struct xlat. (struct xlat): New type definition. * xlat.c (xlat_search, printxval_sized, printxval_searchn_ex, xlat_idx, printxval_indexn_ex, printxval_dispatch_ex, ): Remove. (xlookup): Handle xlat_data based on xlat type. (xlookup_le): New function, replaces xlat_search_eq_or_less and supports all xlat types. (sprintflags_ex, printflags_ex): Update. * xlat/gen.sh (gen_header): Add handling for #sorted, generate new struct xlat descriptor. * defs.h (arp_hardware_types_size, ethernet_protocols_size, inet_protocols_size, evdev_abs_size, xlat_search, xlat_search_eq_or_less, xlat_idx, printxval_searchn_ex, printxval_searchn, printxval_search, printxval_search_ex, printxval_indexn_ex, printxval_indexn, printxval_index, printxval_index_ex, printxval_dispatch_ex, printxval_dispatch): Remove. (enum xlat_style_private_flag_bits): Remove PAF_INDEX_XLAT_SORTED_BIT and PAF_INDEX_XLAT_VALUE_INDEXED_BIT. (enum xlat_style_private_flag): Remove PAF_INDEX_XLAT_SORTED and PAF_INDEX_XLAT_VALUE_INDEXED. (print_array_ex): Remove index_xlat_size argument. (xlookup_le): New declaration. (printxval_ex): New macro. * dyxlat.c (struct dyxlat): Remove used field (use xlat.size instead), embed struct xlat, add pointer to struct xlat_data. (MARK_END): Remove. (dyxlat_alloc, dyxlat_free, dyxlat_get, dyxlat_add_pair): Update in accordance with the structure changes. * evdev.c (evdev_abs_size): Remove. (keycode_ioctl): Use printxval instead of printxval_index. (decode_bitset): Remove. (decode_bitset_): Rename to decode_bitset, remove decode_nr_size and xt arguments, call printxval instead of printxval_dispatch. (bit_ioctl, evdev_read_ioctl): Do not pass xlat type to decode_bitset. * print_fields.h (PRINT_FIELD_XVAL_SORTED_SIZED, PRINT_FIELD_XVAL_INDEX): Remove. * nlattr.h (struct decode_nla_xlat_opts): Remove xlat_size and xt fields. * nlattr.c (decode_nla_meminfo): do not pass PAF_INDEX_XLAT_VALUE_INDEXED flag and netlink_sk_meminfo_indices size in a print_array_ex call. (decode_nla_xval): Call printxval_ex instead of printxval_dispatch_ex. (decode_nla_ether_proto, decode_nla_ip_proto): Do not pass xlat_size and xt fields in opts. (decode_nla_flags): Remove XT_INDEXED unsupported warning. * process.c (struct_user_offsets_data): Rename from struct_user_offsets, change type to struct xlat_data[], remove XLAT_END. (struct_user_offsets): New xlat description. (print_user_offset_addr): Rewrite using xlookup_le. * util.c (print_array_ex): Remove index_xlat_size argument, simply call printxval_ex for index printing. * aio.c (tprint_lio_opcode): Use printxval_ex instead of printxval_indexn_ex. * bpf.c: Use printxval instead of printxval_index; use PRINT_FIELD_XVAL instead of PRINT_FIELD_XVAL_INDEX. * bpf_filter.c (print_bpf_filter_code): Use printxval instead of printxval_index. * ioctl.c (evdev_decode_number): Use printxval instead of printxval_indexn. * kvm.c (kvm_ioctl_decode_check_extension): Use printxval instead of printxval_index. (kvm_ioctl_run_attach_auxstr): Use xlookup instead of xlat_idx. * net.c: Use printxval instead of printxval_search/printxval_index, use printxval_ex instead of printxval_searchn_ex. * netlink_packet_diag.c (decode_packet_diag_msg): Use PRINT_FIELD_XVAL instead of PRINT_FIELD_XVAL_SORTED_SIZED. * netlink_smc_diag.c (decode_smc_diag_shutdown): Remove ARRSZ_PAIR wrapper. (decode_smc_diag_fallback): Use printxval_ex instead of printxval_search_ex.
