From 4acfc287d859bc643c9f9fa63d82e8c90b984d7c Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Thu, 9 May 2019 22:49:28 +0000 Subject: ipc: prefer SYS_ipc when it is defined Linux v5.1 introduced ipc syscalls on targets where previously only SYS_ipc was available, change the logic such that the ipc code keeps using SYS_ipc which works backward compatibly on older kernels. This changes behaviour on microblaze which had both mechanisms, now SYS_ipc will be used instead of separate syscalls. --- src/ipc/shmctl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/ipc/shmctl.c') diff --git a/src/ipc/shmctl.c b/src/ipc/shmctl.c index c951a581..c2b2bb0d 100644 --- a/src/ipc/shmctl.c +++ b/src/ipc/shmctl.c @@ -17,7 +17,7 @@ int shmctl(int id, int cmd, struct shmid_ds *buf) buf = &tmp; } #endif -#ifdef SYS_shmctl +#ifndef SYS_ipc int r = __syscall(SYS_shmctl, id, cmd | IPC_64, buf); #else int r = __syscall(SYS_ipc, IPCOP_shmctl, id, cmd | IPC_64, 0, buf, 0); -- cgit v1.2.1
