This series makes sure we never reallocated a busy extent. This is absolutely needed for a working online discard implementation, and should also speed up large concurrent workloads that would trip over a busy extents a lot. The two most significant patches are from a series Dave posted mored than two years ago, although the main patch to avoid busy ranges in the normal allocator need a lot of bug fixes to survived QA. In addition to that we now also completely avoid resues for AGFL based allocations. While this might not be important from a performance perspectice it is critical for the discard implementation I'm currently working on. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
