Using these helpers allows us to avoid the in-kernel calls to these syscalls: sys_setregid(), sys_setgid(), sys_setreuid(), sys_setuid(), sys_setresuid(), sys_setresgid(), sys_setfsuid(), and sys_setfsgid(). The ksys_ prefix denotes that these function are meant as a drop-in replacement for the syscall. In particular, they use the same calling convention. This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined.
