    Impact: cleanup

    lib/decompress_bunzip2.c depends on slab.h without including it:

    CC lib/decompress_bunzip2.o
    lib/decompress_bunzip2.c: In function ‘start_bunzip’:
    lib/decompress_bunzip2.c:636: error: implicit declaration of function ‘kmalloc’
    lib/decompress_bunzip2.c:636: warning: assignment makes pointer from integer without a cast
    lib/decompress_bunzip2.c: In function ‘bunzip2’:
    lib/decompress_bunzip2.c:682: warning: assignment makes pointer from integer without a cast
    lib/decompress_bunzip2.c:693: warning: assignment makes pointer from integer without a cast
    lib/decompress_bunzip2.c:726: error: implicit declaration of function ‘kfree’
    make[1]: *** [lib/decompress_bunzip2.o] Error 1
    make: *** [lib/] Error 2

    It gets included implicitly currently - but this will not be the
    case with upcoming kmemtrace changes.

  • bc22c17e1   bzip2/lzma: library support for gzip, bzip2 and lzma decompression ... Browse Code »

    Impact: Replaces inflate.c with a wrapper around zlib_inflate; new library code

    This is the first part of the bzip2/lzma patch

    The bzip patch is based on an idea by Christian Ludwig, includes support for
    compressing the kernel with bzip2 or lzma rather than gzip. Both
    compressors give smaller sizes than gzip. Lzma's decompresses faster
    than bzip2.

    It also supports ramdisks and initramfs' compressed using these two
    compressors.

    The functionality has been successfully used for a couple of years by
    the udpcast project

    This version applies to "tip" kernel 2.6.28

    This part contains:
    - changed inflate.c to accomodate rest of patch
    - implementation of bzip2 compression (not used at this stage yet)
    - implementation of lzma compression (not used at this stage yet)
    - Makefile routines to support bzip2 and lzma kernel compression
