       "There's one interseting commit - "libata, freezer: avoid block device
        removal while system is frozen".  It's an ugly hack working around a
        deadlock condition between driver core resume and block layer device
        removal paths through freezer which was made more reproducible by
        writeback being converted to workqueue some releases ago.  The bug has
        nothing to do with libata but it's just an workaround which is easy to
        backport.  After discussion, Rafael and I seem to agree that we don't
        really need kernel freezables - both kthread and workqueue.  There are
        few specific workqueues which constitute PM operations and require
        freezing, which will be converted to use workqueue_set_max_active()
        instead.  All other kernel freezer uses are planned to be removed,
        followed by the removal of kthread and workqueue freezer support,
        hopefully.
      
        Others are device-specific fixes.  The most notable is the addition of
        NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro
        M500 SSDs which otherwise suffers data corruption"

      aio: clean up and fix aio_setup_ring page mapping · 3dc9acb6
      Linus Torvalds authored
      Since commit 36bc08cc ("fs/aio: Add support to aio ring pages
      migration") the aio ring setup code has used a special per-ring backing
      inode for the page allocations, rather than just using random anonymous
      pages.
      
      However, rather than remembering the pages as it allocated them, it
      would allocate the pages, insert them into the file mapping (dirty, so
      that they couldn't be free'd), and then forget about them.  And then to
      look them up again, it would mmap the mapping, and then use
      "get_user_pages()" to get back an array of the pages we just created.
      
      Now, not only is that incredibly inefficient, it also leaked all the
      pages if the mmap failed (which could happen due to excessive number of
      mappings, for example).
      
      So clean it all up, making it much more straightforward.  Also remove
      some left-overs of the previous (broken) mm_populate() usage that was
      removed in commit d6c355c7 ("aio: fix race in ring buffer page
      lookup introduced by page migration support") but left the pointless and
      now misleading MAP_POPULATE flag around.

      mm: do not allocate page->ptl dynamically, if spinlock_t fits to long · 597d795a
      Kirill A. Shutemov authored
      In struct page we have enough space to fit long-size page->ptl there,
      but we use dynamically-allocated page->ptl if size(spinlock_t) is larger
      than sizeof(int).
      
      It hurts 64-bit architectures with CONFIG_GENERIC_LOCKBREAK, where
      sizeof(spinlock_t) == 8, but it easily fits into struct page.

      mm: page_alloc: revert NUMA aspect of fair allocation policy · fff4068c
      Johannes Weiner authored
      Commit 81c0a2bb ("mm: page_alloc: fair zone allocator policy") meant
      to bring aging fairness among zones in system, but it was overzealous
      and badly regressed basic workloads on NUMA systems.
      
      Due to the way kswapd and page allocator interacts, we still want to
      make sure that all zones in any given node are used equally for all
      allocations to maximize memory utilization and prevent thrashing on the
      highest zone in the node.
      
      While the same principle applies to NUMA nodes - memory utilization is
      obviously improved by spreading allocations throughout all nodes -
      remote references can be costly and so many workloads prefer locality
      over memory utilization.  The original change assumed that
      zone_reclaim_mode would be a good enough predictor for that, but it
      turned out to be as indicative as a coin flip.
      
      Revert the NUMA aspect of the fairness until we can find a proper way to
      make it configurable and agree on a sane default.
