      nilfs2: make splice write available again · a35d8f01
      Joachim Henke authored
      Since 5.10, splice() or sendfile() to NILFS2 return EINVAL.  This was
      caused by commit 36e2c742 ("fs: don't allow splice read/write
      without explicit ops").
      
      This patch initializes the splice_write field in file_operations, like
      most file systems do, to restore the functionality.

      mm, slub: better heuristic for number of cpus when calculating slab order · 3286222f
      Vlastimil Babka authored
      When creating a new kmem cache, SLUB determines how large the slab pages
      will based on number of inputs, including the number of CPUs in the
      system.  Larger slab pages mean that more objects can be allocated/free
      from per-cpu slabs before accessing shared structures, but also
      potentially more memory can be wasted due to low slab usage and
      fragmentation.  The rough idea of using number of CPUs is that larger
      systems will be more likely to benefit from reduced contention, and also
      should have enough memory to spare.
      
      Number of CPUs used to be determined as nr_cpu_ids, which is number of
      possible cpus, but on some systems many will never be onlined, thus
      commit 045ab8c9 ("mm/slub: let number of online CPUs determine the
      slub page order") changed it to nr_online_cpus().  However, for kmem
      caches created early before CPUs are onlined, this may lead to
      permamently low slab page sizes.
      
      Vincent reports a regression [1] of hackbench on arm64 systems:
      
        "I'm facing significant performances regression on a large arm64
         server system (224 CPUs). Regressions is also present on small arm64
         system (8 CPUs) but in a far smaller order of magnitude
      
         On 224 CPUs system : 9 iterations of hackbench -l 16000 -g 16
         v5.11-rc4 : 9.135sec (+/- 0.45%)
         v5.11-rc4 + revert this patch: 3.173sec (+/- 0.48%)
         v5.10: 3.136sec (+/- 0.40%)"
      
      Mel reports a regression [2] of hackbench on x86_64, with lockstat suggesting
      page allocator contention:
      
        "i.e. the patch incurs a 7% to 32% performance penalty. This bisected
         cleanly yesterday when I was looking for the regression and then
         found the thread.
      
         Numerous caches change size. For example, kmalloc-512 goes from
         order-0 (vanilla) to order-2 with the revert.
      
         So mostly this is down to the number of times SLUB calls into the
         page allocator which only caches order-0 pages on a per-cpu basis"
      
      Clearly num_online_cpus() doesn't work too early in bootup.  We could
      change the order dynamically in a memory hotplug callback, but runtime
      order changing for existing kmem caches has been already shown as
      dangerous, and removed in 32a6f409 ("mm, slub: remove runtime
      allocation order changes").
      
      It could be resurrected in a safe manner with some effort, but to fix
      the regression we need something simpler.
      
      We could use num_present_cpus() that should be the number of physically
      present CPUs even before they are onlined.  That would work for PowerPC
      [3], which triggered the original commit, but that still doesn't work on
      arm64 [4] as explained in [5].
      
      So this patch tries to determine the best available value without
      specific arch knowledge.
      
       - num_present_cpus() if the number is larger than 1, as that means the
         arch is likely setting it properly
      
       - nr_cpu_ids otherwise
      
      This should fix the reported regressions while also keeping the effect
      of 045ab8c9 for PowerPC systems.  It's possible there are
      configurations where num_present_cpus() is 1 during boot while
      nr_cpu_ids is at the same time bloated, so these (if they exist) would
      keep the large orders based on nr_cpu_ids as was before 045ab8c9.
