ipc: add msgctl syscall/compat_syscall wrappers
Provide ksys_msgctl() and compat_ksys_msgctl() wrappers to avoid in-kernel calls to these syscalls. The ksys_ prefix denotes that these functions are meant as a drop-in replacement for the syscalls. In particular, they use the same calling convention as sys_msgctl() and compat_sys_msgctl(). This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined. For details, see Cc: Al Viro <> Cc: Andrew Morton <> Signed-off-by: Dominik Brodowski <>
