  • 4b6f5d20b   [PATCH] Make most file operations structs in fs/ const ... Browse Code »

    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)

  • fffb60f93   [PATCH] cpuset memory spread: slab cache format ... Browse Code »

    Rewrap the overly long source code lines resulting from the previous
    patch's addition of the slab cache flag SLAB_MEM_SPREAD. This patch
    contains only formatting changes, and no function change.

    Mark file system inode and similar slab caches subject to SLAB_MEM_SPREAD
    memory spreading.

    If a slab cache is marked SLAB_MEM_SPREAD, then anytime that a task that's
    in a cpuset with the 'memory_spread_slab' option enabled goes to allocate
    from such a slab cache, the allocations are spread evenly over all the
    memory nodes (task->mems_allowed) allowed to that task, instead of favoring
    allocation on the node local to the current cpu.

    The following inode and similar caches are marked SLAB_MEM_SPREAD:

    file cache

    fs/ufs/super.c ufs_inode_cache
    net/socket.c sock_inode_cache
    net/sunrpc/rpc_pipe.c rpc_inode_cache

    The choice of which slab caches to so mark was quite simple. I marked
    those already marked SLAB_RECLAIM_ACCOUNT, except for fs/xfs, dentry_cache,
    inode_cache, and buffer_head, which were marked in a previous patch. Even
    though SLAB_RECLAIM_ACCOUNT is for a different purpose, it marks the same
    potentially large file system i/o related slab caches as we need for memory
    spreading.

    Given that the rule now becomes "wherever you would have used a
    SLAB_RECLAIM_ACCOUNT slab cache flag before (usually the inode cache), use
    the SLAB_MEM_SPREAD flag too", this should be easy enough to maintain.
    Future file system writers will just copy one of the existing file system
    slab cache setups and tend to get it right without thinking.

    If anyone needs a fully-functional befs driver, the easiest route to
    that would probably be getting Haiku's befs driver to compile in
    userland as a FUSE fs.

    At any rate, attribute.c can go. It is easy enough to add back in if
    anyone ever wants to do the (relativly minor) refactoring nessisary to
    get it working.

    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!
