Hi folks, After a long time I've managed to get back to these directory speedup patches, originally posted here: https://lore.kernel.org/linux-xfs/20181024225716.19459-1-david@xxxxxxxxxxxxx/ I've addressed all of Christoph's original issues, incorporated his suggestions, updated the benchmark results (same/slightly better improvement) and done more testing on it. The series has been in my test tree since I posted it ~9 months ago and has been in all my benchmarking work over that time. I haven't seen any performance regression as a result of the change of algorithm, but there are a few that go a lot faster.... Comments welcome. -Dave.
