    fs: add ksys_write() helper; remove in-kernel calls to sys_write()

    Using this helper allows us to avoid the in-kernel calls to the sys_write()
    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_write().

    In the near future, the do_mounts / initramfs callers of ksys_write()
    should be converted to use filp_open() and vfs_write() instead.

    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
