fs: add ksys_ioctl() helper; remove in-kernel calls to sys_ioctl()
Using this helper allows us to avoid the in-kernel calls to the sys_ioctl() 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_ioctl(). After careful review, at least some of these calls could be converted to do_vfs_ioctl() in future. 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 http://lkml.kernel.org/r/20180325162527.GA17492@light.dominikbrodowski.net Cc: Alexander Viro <viro@zeniv.linux.org.uk> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
