From b92bea5d2a9481de69bb627a7b442a9f58fca43d Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Sun, 24 Mar 2013 19:59:00 -0400 Subject: Use initalization instead of explicit zeroing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Before, we would initialize many fields twice: first by filling the structure with zeros, and then a second time with the real values. We can let the compiler do the job for us, avoiding one copy. A downside of this patch is that text gets slightly bigger. This is because all zero() calls are effectively inlined: $ size build/.libs/systemd text data bss dec hex filename before 897737 107300 2560 1007597 f5fed build/.libs/systemd after 897873 107300 2560 1007733 f6075 build/.libs/systemd … actually less than 1‰. A few asserts that the parameter is not null had to be removed. I don't think this changes much, because first, it is quite unlikely for the assert to fail, and second, an immediate SEGV is almost as good as an assert. --- src/tmpfiles/tmpfiles.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'src/tmpfiles/tmpfiles.c') diff --git a/src/tmpfiles/tmpfiles.c b/src/tmpfiles/tmpfiles.c index 4e2519d1b5..51827f01af 100644 --- a/src/tmpfiles/tmpfiles.c +++ b/src/tmpfiles/tmpfiles.c @@ -601,11 +601,9 @@ static int recursive_relabel(Item *i, const char *path) { static int glob_item(Item *i, int (*action)(Item *, const char *)) { int r = 0, k; - glob_t g; + glob_t g = {}; char **fn; - zero(g); - errno = 0; if ((k = glob(i->path, GLOB_NOSORT|GLOB_BRACE, NULL, &g)) != 0) { -- cgit v1.2.3-54-g00ecf
