    Phoronix: Linux 2.6.38 Kernel Released

    Just as expected, Linus Torvalds released the Linux 2.6.38 kernel over the night. Since the previous Linux 2.6.38-rc8 release there's been some Btrfs file-system updates and other regression fixes throughout, including two fixes for my AMD Fusion Linux problems. Over the Linux 2.6.37 kernel, there's a lot to be found and to enjoy about this new kernel...

    LZO as compression algorithm for Btrfs. Finally!

    When I first saw news about compressed filesystem in Btrfs and I read it was done with the zlib the first thing I thought was: Why the hell zlib and not LZO? It doesn't make any sense for most uses of a filesystem, except on some really big fat servers. But LZO makes sense everywhere. It's waaay faster and it's compression ratio is very good.

    Phoronix should totally bench and compare the Btrfs mount options now!

    Some tests from the developer (Li Zefan) follow:

    The test copied a linux source tarball (~400M) from an ext4 partition
    to the btrfs partition, and then extracted the tarball.

    (time in second)
    lzo zlib nocompress
    copy: 10.6 21.7 14.9
    extract: 70.1 94.4 66.6

    (data size in MB)
    lzo zlib nocompress
    copy: 185.87 108.69 394.49
    extract: 193.80 132.36 381.21

          I don't have some idea on Linux 2.6.38 Kernel Released so if you get some idea pls share it .
          It's just geek's buzztalking. It only means next version of Ubuntu will have updated software.

              What this means and how do I fix it. It is really annoying and after each oops I get to do fsck for any file errors.

                  ..... ahhaha

                  now I see. But it doesn't really take an AI implementation to do that. A simple conditional statement will do.

                    Of course it will.
