      mm/fadvise.c: do not discard partial pages with POSIX_FADV_DONTNEED · 18aba41c
      Oleg Drokin authored
      I noticed that the logic in the fadvise64_64 syscall is incorrect for
      partial pages.  While first page of the region is correctly skipped if
      it is partial, the last page of the region is mistakenly discarded.
      This leads to problems for applications that read data in
      non-page-aligned chunks discarding already processed data between the
      reads.
      
      A somewhat misguided application that does something like write(XX bytes
      (non-page-alligned)); drop the data it just wrote; repeat gets a
      significant penalty in performance as a result.

      mm: introduce dedicated WQ_MEM_RECLAIM workqueue to do lru_add_drain_all · f3a932ba
      Wang Sheng-Hui authored
      This patch is based on https://patchwork.ozlabs.org/patch/574623/.
      
      Tejun submitted commit 23d11a58 ("workqueue: skip flush dependency
      checks for legacy workqueues") for the legacy create*_workqueue()
      interface.
      
      But some workq created by alloc_workqueue still reports warning on
      memory reclaim, e.g nvme_workq with flag WQ_MEM_RECLAIM set:
      
          workqueue: WQ_MEM_RECLAIM nvme:nvme_reset_work is flushing !WQ_MEM_RECLAIM events:lru_add_drain_per_cpu
          ------------[ cut here ]------------

          kthread+0xd4/0xe8
          ret_from_fork+0x10/0x50
      
      That's because lru_add_drain_all() will schedule the drain work on
      system_wq, whose flag is set to 0, !WQ_MEM_RECLAIM.
      
      Introduce a dedicated WQ_MEM_RECLAIM workqueue to do
      lru_add_drain_all(), aiding in getting memory freed.

      mm: thp: broken page count after commit aa88b68c · 770a5370
      Gerald Schaefer authored
      Christian Borntraeger reported a kernel panic after corrupt page counts,
      and it turned out to be a regression introduced with commit aa88b68c
      ("thp: keep huge zero page pinned until tlb flush"), at least on s390.
      
      put_huge_zero_page() was moved over from zap_huge_pmd() to
      release_pages(), and it was replaced by tlb_remove_page().  However,
      release_pages() might not always be triggered by (the arch-specific)
      tlb_remove_page().
      
      On s390 we call free_page_and_swap_cache() from tlb_remove_page(), and
      not tlb_flush_mmu() -> free_pages_and_swap_cache() like the generic
      version, because we don't use the MMU-gather logic.  Although both
      functions have very similar names, they are doing very unsimilar things,
      in particular free_page_xxx is just doing a put_page(), while
      free_pages_xxx calls release_pages().
      
      This of course results in very harmful put_page()s on the huge zero
      page, on architectures where tlb_remove_page() is implemented in this
      way.  It seems to affect only s390 and sh, but sh doesn't have THP
      support, so the problem (currently) probably only exists on s390.
      
      The following quick hack fixed the issue:
