  • Many struct inode_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • This morning I needed to read a Minix V3 filesystem, but unfortunately my
    2.6.19 did not support that, and neither did the downloaded 2.6.20rc4.

    Fortunately, google told me that Daniel Aragones had already done the work,
    patch found at http://www.terra.es/personal2/danarag/

    Unfortunaly, looking at the patch was painful to my eyes, so I polished it
    a bit before applying. The resulting kernel boots, and reads the
    filesystem it needed to read.

  • This is a conversion to make the various file_operations structs in fs/
    const. Basically a regexp job, with a few manual fixups

    The goal is both to increase correctness (harder to accidentally write to
    shared datastructures) and reducing the false sharing of cachelines with
    things that get dirty in .data (while .rodata is nicely read only and thus
    cache clean)

  • 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!
