      libnvdimm, namespace: fix the type of name variable · 238b323a
      由 Nicolas Iooss 提交于 
      In create_namespace_blk(), the local variable "name" is defined as an
array of NSLABEL_NAME_LEN pointers:

    char *name[NSLABEL_NAME_LEN];

This variable is then used in calls to memcpy() and kmemdup() as if it
were char[NSLABEL_NAME_LEN]. Remove the star in the variable definition
to makes it look right.

      libnvdimm: use consistent naming for request_mem_region() · 450c6633
      由 Dan Williams 提交于 
      Here is an example /proc/iomem listing for a system with 2 namespaces,
one in "sector" mode and one in "memory" mode:

  1fc000000-2fbffffff : Persistent Memory (legacy)
    1fc000000-2fbffffff : namespace1.0
  340000000-34fffffff : Persistent Memory
    340000000-34fffffff : btt0.1

Here is the corresponding ndctl listing:

  # ndctl list
  [
    {
      "dev":"namespace1.0",
      "mode":"memory",
      "size":4294967296,
      "blockdev":"pmem1"
    },
    {
      "dev":"namespace0.0",
      "mode":"sector",
      "size":267091968,
      "uuid":"f7594f86-badb-4592-875f-ded577da2eaf",
      "sector_size":4096,
      "blockdev":"pmem0s"
    }
  ]

Notice that the ndctl listing is purely in terms of namespace devices,
while the iomem listing leaks the internal "btt0.1" implementation
detail. Given that ndctl requires the namespace device name to change
the mode, for example:

  # ndctl create-namespace --reconfig=namespace0.0 --mode=raw --force

...use the namespace name in the iomem listing to keep the claiming
device name consistent across different mode settings.

      libnvdimm: allow a platform to force enable label support · 42237e39
      由 Dan Williams 提交于 
      Platforms like QEMU-KVM implement an NFIT table and label DSMs.
However, since that environment does not define an aliased
configuration, the labels are currently ignored and the kernel registers
a single full-sized pmem-namespace per region. Now that the kernel
supports sub-divisions of pmem regions the labels have a purpose.
Arrange for the labels to be honored when we find an existing / valid
namespace index block.

      libnvdimm: use generic iostat interfaces · 8d7c22ac
      由 Toshi Kani 提交于 
      nd_iostat_start() and nd_iostat_end() implement the same functionality
that generic_start_io_acct() and generic_end_io_acct() already provide.

Change nd_iostat_start() and nd_iostat_end() to call the generic iostat
interfaces.  There is no change in the nd interfaces.
