Subject: [PATCH v5 00/21] libnvdimm: non-volatile memory devices
Changes since v4 [1]:
1/ Rename libnd to libnvdimm, move the implementation from
drivers/block/nd to drivers/nvdimm, and replace the "nd" prefix with
"nvdimm" where it makes sense. For example, the module name and public
header filename for the major library entry points are libnvdimm.ko
and libnvdimm.h respectively. The entry points are prefixed with
"nvdimm" and the primary bus objects are renamed, i.e.
s/nd_bus/nvdimm_bus/ and s/nd_dimm/nvdimm/. The "nd" prefix remains
as a short lead-in identifier for implementation internal items that
are not nvdimms like regions, commands, labels, etc... (Christoph [2])
2/ Move the unit test infrastructure to an external module in
tools/testing/nvdimm. The linker hack received a strong NAK from
Christoph and it is also problematic that an "allmodconfig" build would
result in including the mocked symbols. With the move and conversion to
an external module we keep the unit tests in tree where they can be
maintained effectively without impacting production builds. (Christoph
[2])
3/ Fixup some miscellaneous 0day sparse reports [3]
4/ Rebased on top of linux-pm.git/acpica (Rafael [4])
