       "This is the first -rc pull for the RDMA subsystem.  The patch count is
        high, but they are all smallish patches fixing simple things for the
        most part, and the overall line count of changes here is smaller than
        the patch count would lead a person to believe.
      
        Code is up and running in my labs, including direct testing of cxgb4,
        mlx4, mlx5, ocrdma, and qib.

      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 ]------------
          WARNING: CPU: 0 PID: 6 at SoC/linux/kernel/workqueue.c:2448 check_flush_dependency+0xb4/0x10c
          ...
          check_flush_dependency+0xb4/0x10c

          dma_alloc_from_contiguous+0x38/0x40
          __dma_alloc+0x74/0x25c
          nvme_alloc_queue+0xcc/0x36c

          worker_thread+0x58/0x434
          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.

      When relay_open_buf() fails in relay_open(), code will goto free_bufs,
      but chan is nowhere freed.
