  • a43313668   [PATCH] reiser4: add radix_tree_lookup_slot() ... Browse Code »

    Reiser4 uses radix trees to solve a trouble reiser4_readdir has serving nfs
    requests.

    Unfortunately, radix tree api lacks an operation suitable for modifying
    existing entry. This patch adds radix_tree_lookup_slot which returns pointer
    to found item within the tree. That location can be then updated.

    Both Nick and Christoph Lameter have patches which need this as well.

  • dd0fc66fb   [PATCH] gfp flags annotations - part 1 ... Browse Code »

    - added typedef unsigned int __nocast gfp_t;

    - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
    the same warnings as far as sparse is concerned, doesn't change
    generated code (from gcc point of view we replaced unsigned int with
    typedef) and documents what's going on far better.

  • 32605a181   [PATCH] radix_tag_get(): differentiate between no present node and tag unset cases ... Browse Code »

    Simple patch to radix_tree_tag_get() to return different values for non
    present node and tag unset.

    The function is not used by any in-kernel callers (yet), but this
    information is definitely useful.

  • 201b6264f   [PATCH] radix-tree: Remove unnecessary indirections and clean up code ... Browse Code »

    - There is frequent use of indirections in the radix code. This patch
    removes those indirections, makes the code more readable and allows
    the compilers to generate better code.

    - Removing indirections allows the removal of several casts.

    - Removing indirections allows the reduction of the radix_tree_path
    size from 3 to 2 words.

    - Use pathp-> consistently.

    - Remove unnecessary tmp variable in radix_tree_insert

    - Separate the upper layer processing from the lowest layer in __lookup()
    in order to make it easier to understand what is going on and allow
    compilers to generate better code for the loop.

  • 6c036527a   [PATCH] mostly_read data section ... Browse Code »

    Add a new section called ".data.read_mostly" for data items that are read
    frequently and rarely written to like cpumaps etc.

    If these maps are placed in the .data section then these frequenly read
    items may end up in cachelines with data is is frequently updated. In that
    case all processors in an SMP system must needlessly reload the cachelines
    again and again containing elements of those frequently used variables.

    The ability to share these cachelines will allow each cpu in an SMP system
    to keep local copies of those shared cachelines thereby optimizing
    performance.

    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!
