  • 93fd85d00   identify_ramdisk_image(): correct typo about return value in comment ... Browse Code »

    identify_ramdisk_image() returns 0 (not -1) if a gzipped ramdisk is found:

    if (buf[0] == 037 && ((buf[1] == 0213) || (buf[1] == 0236))) {
    printk(KERN_NOTICE
    "RAMDISK: Compressed image found at block %d\n",
    start_block);
    nblocks = 0;
    ^^^^^^^^^^^
    goto done;
    }

    ...

    done:
    sys_lseek(fd, start_block * BLOCK_SIZE, 0);
    kfree(buf);
    return nblocks;
    ^^^^^^^^^^^^^^

    Hence correct the typo in the comment, which has existed since the
    addition of compressed ramdisk support in 1.3.48.

  • 2d6ffcca6   inflate: refactor inflate malloc code ... Browse Code »

    Inflate requires some dynamic memory allocation very early in the boot
    process and this is provided with a set of four functions:
    malloc/free/gzip_mark/gzip_release.

    The old inflate code used a mark/release strategy rather than implement
    free. This new version instead keeps a count on the number of outstanding
    allocations and when it hits zero, it resets the malloc arena.

    This allows removing all the mark and release implementations and unifying
    all the malloc/free implementations.

    The architecture-dependent code must define two addresses:
    - free_mem_ptr, the address of the beginning of the area in which
    allocations should be made
    - free_mem_end_ptr, the address of the end of the area in which
    allocations should be made. If set to 0, then no check is made on
    the number of allocations, it just grows as much as needed

    The architecture-dependent code can also provide an arch_decomp_wdog()
    function call. This function will be called several times during the
    decompression process, and allow to notify the watchdog that the system is
    still running. If an architecture provides such a call, then it must
    define ARCH_HAS_DECOMP_WDOG so that the generic inflate code calls
    arch_decomp_wdog().

    Work initially done by Matt Mackall, updated to a recent version of the
    kernel and improved by me.

    There seems to be little point in explicitly setting, then testing the macro
    BUILD_CRAMDISK within the context of a single source file.

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
