Subject: [GIT PULL] libnvdimm fix for 4.13-final
Date: Wed, 30 Aug 2017 21:37:54 +0000 [thread overview]
Message-ID: <1504129067.3089.3.camel@intel.com> (raw)
Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm libnvdimm-fixes
...to receive a single patch removing some structure definitions from a
uapi header file. These payloads are never processed directly by the
kernel they are simply passed through an ioctl as opaque blobs to the
ACPI _DSM (Device Specific Method) interface.
Userspace should not be depending on the kernel to define these
payloads. We will instead provide these definitions via the existing
libndctl (https://github.com/pmem/ndctl) project that has NVDIMM
command helpers and other definitions.

libnvdimm: clean up command definitions
Remove the command payloads that do not have an associated libnvdimm
ioctl. I.e. remove the payloads that would only ever be carried in the
ND_CMD_CALL envelope. This prevents userspace from growing unnecessary
dependencies on this kernel header when userspace already has everything
it needs to craft and send these commands.
