Subject: [PATCH v2 0/3] misc updates for Address Range Scrub
Date: Fri, 30 Sep 2016 14:10:00 -0600	[thread overview]
Message-ID: <1475266203-18559-1-git-send-email-vishal.l.verma@intel.com> (raw)

Changes in v2:
- Change the 'scrub' attribute to only show the number of completed scrubs,
  and start a new one ondemand. (Dan)
- Add a new attribute 'hw_error_scrub' which controls whether or not a full
  scrub will run on hardware memory errors. (Dan)

Patch 1 changes the default behaviour on machine check exceptions to
just adding the error address to badblocks accounting instead of starting
a full ARS. The old behaviour can be enabled via sysfs.

Patch 2 and 3 fix a problem where stale badblocks could show up after an
on-demand ARS or an MCE triggered scrub because when clearing poison, we
didn't clear the internal nvdimm_bus->poison_list.

Vishal Verma (3):
  nfit: don't start a full scrub by default for an MCE
  pmem: reduce kmap_atomic sections to the memcpys only
  libnvdimm: clear the internal poison_list when clearing badblocks
