    Torvalds had spent 18 months running a broken version of his own fix for the page-cache reference-counting bottleneck, while other developers had encountered problems with their approaches. The new patches eliminate folio reference-count operations from a common buffered-read path, although Torvalds warned that the benchmark gains would be considerably smaller in real-world workloads.

      They need to add an analogy in there…

      “The problem is with the folio reference-count operations from a common buffered-read path”
