Subject: [PATCH] libnvdimm: clean up command definitions
Date: Mon, 28 Aug 2017 08:45:32 -0700	[thread overview]
Message-ID: <150393513271.10003.253995897844648312.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)

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.
