  • 87c4e1926   fs: add do_mknodat() helper and ksys_mknod() wrapper; remove in-kernel calls to syscall ... Browse Code »

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

    Introducing the ksys_mknod() wrapper allows us to avoid the in-kernel
    calls to sys_mknod() 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_mknod().

    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

  • 562f5e638   init: mark __user address space on string literals ... Browse Code »

    When calling syscall service routines in kernel, some of arguments should
    be user pointers but were missing __user markup on string literals. Add
    it. Removes some sparse warnings.

  • c33df4eaa   [PATCH] disable init/initramfs.c ... Browse Code »

    The file init/initramfs.c is always compiled and linked in the kernel
    vmlinux even when BLK_DEV_RAM and BLK_DEV_INITRD are disabled and the
    system isn't using any form of an initramfs or initrd. In this situation
    the code is only used to unpack a (static) default initial rootfilesystem.
    The current init/initramfs.c code. usr/initramfs_data.o compiles to a size
    of ~15 kbytes. Disabling BLK_DEV_RAM and BLK_DEV_INTRD shrinks the kernel
    code size with ~60 Kbytes.

    This patch avoids compiling in the code and data for initramfs support if
    CONFIG_BLK_DEV_INITRD is not defined. Instead of the initramfs code and
    data it uses a small routine in init/noinitramfs.c to setup an initial
    static default environment for mounting a rootfilesystem later on in the
    kernel initialisation process. The new code is: 164 bytes of size.

    The patch is separated in two parts:
    1) doesn't compile initramfs code when CONFIG_BLK_DEV_INITRD is not set
    2) changing all plaforms vmlinux.lds.S files to not reserve an area of
    PAGE_SIZE when CONFIG_BLK_DEV_INITRD is not set.
