From b92bea5d2a9481de69bb627a7b442a9f58fca43d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-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/remount-fs/remount-fs.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/remount-fs') diff --git a/src/remount-fs/remount-fs.c b/src/remount-fs/remount-fs.c index b49d095cb..f432718d6 100644 --- a/src/remount-fs/remount-fs.c +++ b/src/remount-fs/remount-fs.c @@ -129,10 +129,9 @@ int main(int argc, char *argv[]) { } while (!hashmap_isempty(pids)) { - siginfo_t si; + siginfo_t si = {}; char *s; - zero(si); if (waitid(P_ALL, 0, &si, WEXITED) < 0) { if (errno == EINTR) -- cgit v1.2.3
