      libnvdimm, label: convert label tracking to a linked list · ae8219f1
      Dan Williams 提交于
      In preparation for enabling multiple namespaces per pmem region, convert
      the label tracking to use a linked list.  In particular this will allow
      select_pmem_id() to move labels from the unvalidated state to the
      validated state.  Currently we only track one validated set per-region.

      libnvdimm, region: move region-mapping input-paramters to nd_mapping_desc · 44c462eb
      Dan Williams 提交于
      Before we add more libnvdimm-private fields to nd_mapping make it clear
      which parameters are input vs libnvdimm internals. Use struct
      nd_mapping_desc instead of struct nd_mapping in nd_region_desc and make
      struct nd_mapping private to libnvdimm.

      libnvdimm: clear the internal poison_list when clearing badblocks · e046114a
      Vishal Verma 提交于
      nvdimm_clear_poison cleared the user-visible badblocks, and sent
      commands to the NVDIMM to clear the areas marked as 'poison', but it
      neglected to clear the same areas from the internal poison_list which is
      used to marshal ARS results before sorting them by namespace. As a
      result, once on-demand ARS functionality was added:
      
      37b137ff nfit, libnvdimm: allow an ARS scrub to be triggered on demand
      
      A scrub triggered from either sysfs or an MCE was found to be adding
      stale entries that had been cleared from gendisk->badblocks, but were
      still present in nvdimm_bus->poison_list. Additionally, the stale entries
      could be triggered into producing stale disk->badblocks by simply disabling
      and re-enabling the namespace or region.
      
      This adds the missing step of clearing poison_list entries when clearing
      poison, so that it is always in sync with badblocks.

      pmem: reduce kmap_atomic sections to the memcpys only · bd697a80
      Vishal Verma 提交于
      pmem_do_bvec used to kmap_atomic at the begin, and only unmap at the
      end. Things like nvdimm_clear_poison may want to do nvdimm subsystem
      bookkeeping operations that may involve taking locks or doing memory
      allocations, and we can't do that from the atomic context. Reduce the
      atomic context to just what needs it - the memcpy to/from pmem.

      nfit: don't start a full scrub by default for an MCE · 9ffd6350
      Vishal Verma 提交于
      Starting a full Address Range Scrub (ARS) on hitting a memory error
      machine check exception may not always be desirable. Provide a way
      through sysfs to toggle the behavior between just adding the address
      (cache line) where the MCE happened to the poison list and doing a full
      scrub. The former (selective insertion of the address) is done
      unconditionally.
