From 0e0345b77ac4605d5447b252d220e4a2ee118da7 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Thu, 15 Apr 2021 20:36:07 +0300 Subject: kbuild: redo fake deps at include/config/*.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Make include/config/foo/bar.h fake deps files generation simpler. * delete .h suffix those aren't header files, shorten filenames, * delete tolower() Linux filesystems can deal with both upper and lowercase filenames very well, * put everything in 1 directory Presumably 'mkdir -p' split is from dark times when filesystems handled huge directories badly, disks were round adding to seek times. x86_64 allmodconfig lists 12364 files in include/config. ../obj/include/config/ ├── 104_QUAD_8 ├── 60XX_WDT ├── 64BIT ... ├── ZSWAP_DEFAULT_ON ├── ZSWAP_ZPOOL_DEFAULT └── ZSWAP_ZPOOL_DEFAULT_ZBUD 0 directories, 12364 files Signed-off-by: Alexey Dobriyan Signed-off-by: Masahiro Yamada --- scripts/kconfig/confdata.c | 15 +++++---------- 1 file changed, 5 insertions(+), 10 deletions(-) (limited to 'scripts/kconfig') diff --git a/scripts/kconfig/confdata.c b/scripts/kconfig/confdata.c index 2568dbe16ed6..c7b7e1c62a9c 100644 --- a/scripts/kconfig/confdata.c +++ b/scripts/kconfig/confdata.c @@ -130,19 +130,14 @@ static size_t depfile_prefix_len; static int conf_touch_dep(const char *name) { int fd, ret; - const char *s; - char *d, c; + char *d; - /* check overflow: prefix + name + ".h" + '\0' must fit in buffer. */ - if (depfile_prefix_len + strlen(name) + 3 > sizeof(depfile_path)) + /* check overflow: prefix + name + '\0' must fit in buffer. */ + if (depfile_prefix_len + strlen(name) + 1 > sizeof(depfile_path)) return -1; d = depfile_path + depfile_prefix_len; - s = name; - - while ((c = *s++)) - *d++ = (c == '_') ?
