From 3d65661a494a11266500c2532b4f163537c379db Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Tue, 20 Mar 2018 20:06:04 +0100 Subject: ipc: add msgget syscall wrapper Provide ksys_msgget() wrapper to avoid in-kernel calls to this syscall. The ksys_ prefix denotes that this function is meant as a drop-in replacement for the syscall. In particular, it uses the same calling convention as sys_msgget(). This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined.
