    - The CPU scheduler changes in -mm (sched-domains) have been hanging about
    for too long. I had been hoping that the people who care about SMT and
    NUMA performance would have some results by now but all seems to be silent.

    I do not wish to merge these up until the big-iron guys can say that they
    suit their requirements, with a reasonable expectation that we will not
    need to churn this code later in the 2.6 series.

    So. If you have been testing, please speak up. If you have not been
    testing, please do so.


    - Major surgery against the pagecache, radix-tree and writeback code. This
    work is to address the O_DIRECT-vs-buffered data exposure horrors which
    we've been struggling with for months.

    As a side-effect, 32 bytes are saved from struct inode and eight bytes
    are removed from struct page.

    This change will break any arch code which is using page->list and will
    also break any arch code which is using page->lru of memory which was
    obtained from slab.

    It seems to work OK here, but I suggest people not rush out and convert
    all of the corporate finance department's servers to 2.6.4-mm1.

    The basic problem which we (mainly Daniel McNeil) have been struggling
    with is in getting a really reliable fsync() across the page lists while
    other processes are performing writeback against the same file. It's like
    juggling four bars of wet soap with your eyes shut while someone is
    whacking you with a baseball bat. Daniel pretty much has the problem
    plugged but I suspect that's just because we don't have testcases to
    trigger the remaining problems. The complexity and additional locking
    which those patches add is worrisome.

    So the approach taken here is to remove the page lists altogether and
    replace the list-based writeback and wait operations with in-order
    radix-tree walks.

    The radix-tree code has been enhanced to support "tagging" of pages, for
    later searches for pages which have a particular tag set. This means that
    we can ask the radix tree code "find me the next 16 dirty pages starting at
    pagecache index N" and it will do that in O(log64(N)) time.

    This affects I/O scheduling potentially quite significantly. It is no
    longer the case that the kernel will submit pages for I/O in the order in
    which the application dirtied them. We instead submit them in file-offset
    order all the time.

    This is likely to be advantageous when applications are seeking all over
    a large file randomly writing small amounts of data. I haven't performed
    much benchmarking, but tiobench random write throughput seems to be
    increased by 30%. Other tests appear to be unaltered. dbench may have got
    10-20% quicker, but it's variable.

    There is one large file which everyone seeks all over randomly writing
    small amounts of data: the blockdev mapping which caches filesystem
    metadata. The kernel's IO submission patterns for this are now ideal.


    Because writeback and wait-for-writeback use a tree walk instead of a
    list walk they are no longer livelockable. This probably means that we no
    longer need to hold i_sem across O_SYNC writes and perhaps fsync() and
    fdatasync(). This may be beneficial for databases: multiple processes
    writing and syncing different parts of the same file at the same time can
    now all submit and wait upon writes to just their own little bit of the
    file, so we can get a lot more data into the queues.

    It is trivial to implement a part-file-fdatasync() as well, so
    applications can say "sync the file from byte N to byte M", and multiple
    applications can do this concurrently. This is easy for ext2 filesystems,
    but probably needs lots of work for data-journalled filesystems and XFS and
    it probably doesn't offer much benefit over an i_semless O_SYNC write.

    - Dropped the hotplug CPU patches: bits of them were merged into Linus's
    kernel and things broke.

    - Various little fixes as usual.
