2016-02-12modprobe: only parse files that end in .confMike Frysinger
This matches behavior with kmod which has been the standard for a long time at this point. URL: https://bugs.busybox.net/8021 Reported-by: Jö <jorrit@jorrit.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2015-11-05modutils: merge module_entry and module_info to commonTimo Teräs
This merges the in-memory module info structures of modprobe and depmod. This allows sharing hashing by modulename code improving depmod runtime with almost factor of 2x. function old new delta get_or_add_modentry - 17 +17 do_modprobe 590 601 +11 moddb_get_or_create - 10 +10 load_modules_dep 195 205 +10 moddb_get - 7 +7 add_probe 81 78 -3 modprobe_main 721 714 -7 depmod_main 553 543 -10 config_file_action 434 421 -13 helper_get_module 160 144 -16 parse_module 343 320 -23 order_dep_list 105 82 -23 ------------------------------------------------------------------------------ (add/remove: 3/0 grow/shrink: 2/7 up/down: 55/-95) Total: -40 bytes Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
