Subject: [PATCH v3 06/17] Use msgget syscall for Linux implementation
Date: Tue, 08 Nov 2016 20:31:00 -0000 [thread overview]
Message-ID: <1478637007-31212-7-git-send-email-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <1478637007-31212-1-git-send-email-adhemerval.zanella@linaro.org>
Changes from previous version
- Remove msgget from syscalls.list.
--
This patch add a direct call to msgget syscall if it is supported by
kernel features.
hecked on x86_64, i686, powerpc64le, aarch64, and armhf.
* sysdeps/unix/sysv/linux/alpha/syscalls.list (msgget): Remove.
* sysdeps/unix/sysv/linux/arm/syscalls.list (msgget): Likewise.
* sysdeps/unix/sysv/linux/generic/syscalls.list (msgget): Likewise.
* sysdeps/unix/sysv/linux/hppa/syscalls.list (msgget): Likewise.
* sysdeps/unix/sysv/linux/ia64/syscalls.list (msgget): Likewise.
* sysdeps/unix/sysv/linux/microblaze/syscalls.list (msgget): Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/syscalls.list (msgget):
Likewise.
* sysdeps/unix/sysv/linux/s390/s390-64/syscalls.list (msgget):
Likewise.
* sysdeps/unix/sysv/linux/x86_64/syscalls.list (msgget): Likewise.
* sysdeps/unix/sysv/linux/msgget.c (msgget): Use msgget syscall if
define.
