H A Dinitramfs.cb724e846 Sun Mar 11 05:34:49 CDT 2018 Dominik Brodowski <linux@dominikbrodowski.net> fs: add do_symlinkat() helper and ksys_symlink() wrapper; remove in-kernel calls to syscall

Using the fs-internal do_symlinkat() helper allows us to get rid of
fs-internal calls to the sys_symlinkat() syscall.

Introducing the ksys_symlink() wrapper allows us to avoid the in-kernel
calls to the sys_symlink() 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_symlink().

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
