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
<kernel-features.h>.
(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
<kernel-features.h>.
(__opensock) [SOCK_CLOEXEC]: Make code unconditional.
(__opensock) [!__ASSUME_SOCK_CLOEXEC]: Remove conditional code.
