  • 20c2df83d   mm: Remove slab destructors from kmem_cache_create(). ... Browse Code »

    Slab destructors were no longer supported after Christoph's
    c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
    BUGs for both slab and slub, and slob never supported them
    either.

    This rips out support for the dtor pointer from kmem_cache_create()
    completely and fixes up every single callsite in the kernel (there were
    about 224, not including the slab allocator definitions themselves,
    or the documentation references).

  • 0f7fc9e4d   [PATCH] VFS: change struct file to use struct path ... Browse Code »

    This patch changes struct file to use struct path instead of having
    independent pointers to struct dentry and struct vfsmount, and converts all
    users of f_{dentry,vfsmnt} in fs/ to use f_path.{dentry,mnt}.

    Additionally, it adds two #define's to make the transition easier for users of
    the f_dentry and f_vfsmnt.

  • e18b890bb   [PATCH] slab: remove kmem_cache_t ... Browse Code »

    Replace all uses of kmem_cache_t with struct kmem_cache.

    The patch was generated using the following script:

    #!/bin/sh
    #
    # Replace one string by another in all the kernel sources.
    #

    set -e

    for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do
    quilt add $file
    sed -e "1,\$s/$1/$2/g" $file >/tmp/$$
    mv /tmp/$$ $file
    quilt refresh
    done

    The script was run like this

    sh replace kmem_cache_t "struct kmem_cache"

  • fa3536cc1   [PATCH] Use __read_mostly on some hot fs variables ... Browse Code »

    I discovered on oprofile hunting on a SMP platform that dentry lookups were
    slowed down because d_hash_mask, d_hash_shift and dentry_hashtable were in
    a cache line that contained inodes_stat. So each time inodes_stats is
    changed by a cpu, other cpus have to refill their cache line.

    This patch moves some variables to the __read_mostly section, in order to
    avoid false sharing. RCU dentry lookups can go full speed.

    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!
