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. Cheers, Dave. -- Dave Chinner Principal Engineer SGI Australian Software Group
