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/msgrcv.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/ipc/msgrcv.c') diff --git a/src/ipc/msgrcv.c b/src/ipc/msgrcv.c index 0a344e56..9d1034b1 100644 --- a/src/ipc/msgrcv.c +++ b/src/ipc/msgrcv.c @@ -4,7 +4,7 @@ ssize_t msgrcv(int q, void *m, size_t len, long type, int flag) { -#ifdef SYS_msgrcv +#ifndef SYS_ipc return syscall_cp(SYS_msgrcv, q, m, len, type, flag); #else return syscall_cp(SYS_ipc, IPCOP_msgrcv, q, len, flag, ((long[]){ (long)m, type })); -- cgit v1.2.1
