Changes from previous version: - Use __ASSUME_SYSVIPC_SYSCALL instead of __NR_syscall to issue the wired syscall or the ipc one. -- This patch add a direct call to semget syscall if it is supported by kernel features. hecked on x86_64, i686, powerpc64le, aarch64, and armhf. * sysdeps/unix/sysv/linux/semget.c (semget): Use semget syscall if it is defined. --- ChangeLog | 3 +++ sysdeps/unix/sysv/linux/semget.c | 11 ++++++----- 2 files changed, 9 insertions(+), 5 deletions(-) -- 2.7.4
