#     Revert "vfs: Delete the associated dentry when deleting a file"
#     
#     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.
