      dm: add dax_device and dax_operations support · f26c5719
      Dan Williams authored
      Allocate a dax_device to represent the capacity of a device-mapper
      instance. Provide a ->direct_access() method via the new dax_operations
      indirection that mirrors the functionality of the current direct_access
      support via block_device_operations.  Once fs/dax.c has been converted
      to use dax_operations the old dm_blk_direct_access() will be removed.
      
      A new helper dm_dax_get_live_target() is introduced to separate some of
      the dm-specifics from the direct_access implementation.
      
      This enabling is only for the top-level dm representation to upper
      layers. Converting target direct_access implementations is deferred to a
      separate patch.

      dax: introduce dax_direct_access() · b0686260
      Dan Williams authored
      Replace bdev_direct_access() with dax_direct_access() that uses
      dax_device and dax_operations instead of a block_device and
      block_device_operations for dax. Once all consumers of the old api have
      been converted bdev_direct_access() will be deleted.
      
      Given that block device partitioning decisions can cause dax page
      alignment constraints to be violated this also introduces the
      bdev_dax_pgoff() helper. It handles calculating a logical pgoff relative
      to the dax_device and also checks for page alignment.

      x86, pmem: fix broken __copy_user_nocache cache-bypass assumptions · 11e63f6d
      Dan Williams authored
      Before we rework the "pmem api" to stop abusing __copy_user_nocache()
      for memcpy_to_pmem() we need to fix cases where we may strand dirty data
      in the cpu cache. The problem occurs when copy_from_iter_pmem() is used
      for arbitrary data transfers from userspace. There is no guarantee that
      these transfers, performed by dax_iomap_actor(), will have aligned
      destinations or aligned transfer lengths. Backstop the usage
      __copy_user_nocache() with explicit cache management in these unaligned
      cases.
      
      Yes, copy_from_iter_pmem() is now too big for an inline, but addressing
      that is saved for a later patch that moves the entirety of the "pmem
      api" into the pmem driver directly.

      is needed.
      
      Note that this is not a problem in the blk case since that path never
      calls nvdimm_clear_poison().

      libnvdimm: fix blk free space accounting · fe514739
      Dan Williams authored
      Commit a1f3e4d6 "libnvdimm, region: update nd_region_available_dpa()
      for multi-pmem support" reworked blk dpa (DIMM Physical Address)
      accounting to comprehend multiple pmem namespace allocations aliasing
      with a given blk-dpa range.
      
      The following call trace is a result of failing to account for allocated
      blk capacity.
      
       WARNING: CPU: 1 PID: 2433 at tools/testing/nvdimm/../../../drivers/nvdimm/names
      4 size_store+0x6f3/0x930 [libnvdimm]

      If a given blk-dpa allocation does not alias with any pmem ranges then
      the full allocation should be accounted as busy space, not the size of
      the current pmem contribution to the region.
      
      The thinkos that led to this confusion was not realizing that the struct
      resource management is already guaranteeing no collisions between pmem
      allocations and blk allocations on the same dimm. Also, we do not try to
      support blk allocations in aliased pmem holes.
      
      This patch also fixes a case where the available blk goes negative.

       "This has been a slow -rc cycle for the RDMA subsystem. We really
        haven't had a lot of rc fixes come in. This pull request is the first

        and it's still only about 20 patches. The fix for the minor breakage
        cause by the dma mapping patchset is in here, as well as a couple
        other potential oops fixes, but the rest is more minor.
      
        Summary:
      
         - fix for dma_ops change in this kernel, resolving the s390, powerpc,
           and IOMMU operation

        While I'm not excited that we need to be sending you something this
        large during the -rcX phase, it does fix some very real, and very
        tangled, problems relating to locking, backlog queues, and the audit
        daemon connection.
      
        This code has passed our testsuite without problem and it has held up
        to my ad-hoc stress tests (arguably better than the existing code),
