# This reverts commit 681ce8623567ba7e7333908e9826b77145312dda. # # We gave it a try, but it turns out the kernel test robot did in fact # find performance regressions for it, so we'll have to look at the more # involved alternative fixes for Yafang Shao's Elasticsearch load issue. # # There were several alternatives discussed, they just weren't as simple # as this first attempt. # # The report is of a -7.4% regression of filebench.sum_operations/s, which # appears significant enough to trigger my "this patch may get reverted if # somebody finds a performance regression on some other load" rule. # # So it's still the case that we should end up deleting dentries more # aggressively - or just be better at pruning them later - but it needs a # bit more finesse than this simple thing. # # Link: https://lore.kernel.org/all/202405291318.4dfbb352-oliver.sang@intel.com/ #
