    Subject[PATCH 0/9]: Various XFS inode clustering improvements

    Normally I wouldn't bother cc'ing lkml on XFS changes, however a
    couple of these patches touch generic code. The changes to generic
    code are introducing a WRITE_META bio type and
    radix_tree_gang_lookup_range() and hence the wider ditribution.
    This patch set is against the current xfs-dev tree so bits of
    it may not apply to current mainline.

    Overall, the patch set is focussed on improving the XFS inode
    cache and clustering code. It reduces memory usage of the
    cache by 5-10% and improves performance on some workloads
    by 10-15%.

    Comments welcome.
