Subject: [PATCH v7 00/16] libnvdimm: non-volatile memory devices
A new sub-system in support of non-volatile memory storage devices.
Stephen, please add libnvdimm-for-next to -next:
git://git.kernel.org/pub/scm/linux/kernel/git/djbw/nvdimm libnvdimm-for-next
Changes since v6 [1]:
1/ Deferred the patches dependent on ->rw_bytes() (BTT - stacked block
driver, BLK - mmio aperture windows driver, NFIT_TEST - unit test
infrastructure for all libnvdimm + nfit components) to their own
patchset. Make the ->rw_bytes() implementation the first patch in
that series (Christoph)
2/ Collected acks from Christoph and Rafael!
3/ Add a HAS_IOMEM dependency to CONFIG_BLK_DEV_PMEM following commit
b6f2098fb708 "block: pmem: Add dependency on HAS_IOMEM" in 4.1-rc8.
4/ Move libnvdimm to subsys_initcall() and move arch/x86/kernel/pmem.c
back to device_initcall(). This allows ACPI_NFIT to be built-in.
(Linda)
5/ Drop the ACPI_DRIVER_ALL_NOTIFY_EVENTS flag in the nfit driver.
(Rafael)
6/ Reference count the nvdimm_drvdata object. This fixes a bug that was
found when the unit tests were extended to test disabling an nvdimm
while a region device still had references to label data.
