  • 870f48179   [PATCH] replace inode_update_time with file_update_time ... Browse Code »

    To allow various options to work per-mount instead of per-sb we need a
    struct vfsmount when updating ctime and mtime. This preparation patch
    replaces the inode_update_time routine with a file_update_atime routine so
    we can easily get at the vfsmount. (and the file makes more sense in this
    context anyway). Also get rid of the unused second argument - we always
    want to update the ctime when calling this routine.

  • 5160ee6fc   [PATCH] shrink dentry struct ... Browse Code »

    Some long time ago, dentry struct was carefully tuned so that on 32 bits
    UP, sizeof(struct dentry) was exactly 128, ie a power of 2, and a multiple
    of memory cache lines.

    Then RCU was added and dentry struct enlarged by two pointers, with nice
    results for SMP, but not so good on UP, because breaking the above tuning
    (128 + 8 = 136 bytes)

    This patch reverts this unwanted side effect, by using an union (d_u),
    where d_rcu and d_child are placed so that these two fields can share their
    memory needs.

    At the time d_free() is called (and d_rcu is really used), d_child is known
    to be empty and not touched by the dentry freeing.

    Lockless lookups only access d_name, d_parent, d_lock, d_op, d_flags (so
    the previous content of d_child is not needed if said dentry was unhashed
    but still accessed by a CPU because of RCU constraints)

    As dentry cache easily contains millions of entries, a size reduction is
    worth the extra complexity of the ugly C union.

  • 8c744fb83   [PATCH] add a file_permission helper ... Browse Code »

    A few more callers of permission() just want to check for a different access
    pattern on an already open file. This patch adds a wrapper for permission()
    that takes a file in preparation of per-mount read-only support and to clean
    up the callers a little. The helper is not intended for new code, everything
    without the interface set in stone should use vfs_permission()

  • fef266580   [PATCH] update filesystems for new delete_inode behavior ... Browse Code »

    Update the file systems in fs/ implementing a delete_inode() callback to
    call truncate_inode_pages(). One implementation note: In developing this
    patch I put the calls to truncate_inode_pages() at the very top of those
    filesystems delete_inode() callbacks in order to retain the previous
    behavior. I'm guessing that some of those could probably be optimized.

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    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!
