From d7109027508c8ef5f4218abc737fcb1a411c2bd3 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 20 Jun 2014 23:22:08 +0000 Subject: Remove __ASSUME_SOCK_CLOEXEC / SOCK_CLOEXEC conditionals in Linux-specific code. This patch removes conditionals on __ASSUME_SOCK_CLOEXEC, and on SOCK_CLOEXEC being defined, in Linux-specific code, now that all supported Linux kernel versions can be assumed to have this functionality. (The macro is also used in OS-independent code and is not defined for Hurd.) Tested x86_64 that the disassembly of installed shared libraries is unchanged by this patch. * nptl/sysdeps/unix/sysv/linux/mq_notify.c: Do not include . (init_mq_netlink): Remove conditional have_sock_cloexec definitions. Remove code conditional on have_sock_cloexec < 0. (init_mq_netlink) [!SOCK_CLOEXEC]: Remove conditional code. (init_mq_netlink) [!__ASSUME_SOCK_CLOEXEC]: Likewise. * sysdeps/unix/sysv/linux/opensock.c: Do not include . (__opensock) [SOCK_CLOEXEC]: Make code unconditional. (__opensock) [!__ASSUME_SOCK_CLOEXEC]: Remove conditional code. --- sysdeps/unix/sysv/linux/opensock.c | 39 ++------------------------------------ 1 file changed, 2 insertions(+), 37 deletions(-) (limited to 'sysdeps/unix/sysv/linux/opensock.c') diff --git a/sysdeps/unix/sysv/linux/opensock.c b/sysdeps/unix/sysv/linux/opensock.c index bcf7f5fc40..4894bf995f 100644 --- a/sysdeps/unix/sysv/linux/opensock.c +++ b/sysdeps/unix/sysv/linux/opensock.c @@ -21,7 +21,6 @@ #include #include #include -#include /* Return a socket of any type.
