+LIBNVDIMM Maintainer Entry Profile
+==================================
+
+Overview
+--------
+The libnvdimm subsystem manages persistent memory across multiple
+architectures. The mailing list, is tracked by patchwork here:
+https://patchwork.kernel.org/project/linux-nvdimm/list/
+...and that instance is configured to give feedback to submitters on
+patch acceptance and upstream merge. Patches are merged to either the
+'libnvdimm-fixes', or 'libnvdimm-for-next' branch. Those branches are
+available here:
+https://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm.git/
+
+In general patches can be submitted against the latest -rc, however if
+the incoming code change is dependent on other pending changes then the
+patch should be based on the libnvdimm-for-next branch. However, since
+persistent memory sits at the intersection of storage and memory there
+are cases where patches are more suitable to be merged through a
+Filesystem or the Memory Management tree. When in doubt copy the nvdimm
+list and the maintainers will help route.
+
+Submissions will be exposed to the kbuild robot for compile regression
+testing. It helps to get a success notification from that infrastructure
+before submitting, but it is not required.
+
+
+Submit Checklist Addendum
+-------------------------
+There are unit tests for the subsystem via the ndctl utility:
+https://github.com/pmem/ndctl
+Those tests need to be passed before the patches go upstream, but not
+necessarily before initial posting. Contact the list if you need help
+getting the test environment set up.
+
+### ACPI Device Specific Methods (_DSM)
+Before patches enabling for a new _DSM family will be considered it must
+be assigned a format-interface-code from the NVDIMM Sub-team of the ACPI
+Specification Working Group. In general, the stance of the subsystem is
+to push back on the proliferation of NVDIMM command sets, do strongly
+consider implementing support for an existing command set. See
+drivers/acpi/nfit/nfit.h for the set of support command sets.
+
+
+Key Cycle Dates
+---------------
+New submissions can be sent at any time, but if they intend to hit the
+next merge window they should be sent before -rc4, and ideally
+stabilized in the libnvdimm-for-next branch by -rc6. Of course if a
+patch set requires more than 2 weeks of review -rc4 is already too late
+and some patches may require multiple development cycles to review.
+
+
+Review Cadence
+--------------
+In general, please wait up to one week before pinging for feedback. A
+private mail reminder is preferred. Alternatively ask for other
+developers that have Reviewed-by tags for libnvdimm changes to take a
+look and offer their opinion.
