Re: [PATCH v3] libnvdimm, region: sysfs trigger for nvdimm_flush()

We also still seem to need a discovery mechanism as I've had

about "how do I tell if my system supports deep flush?". That's where
sysfs is much better than an ioctl. The need for deep flush discovery
tips the scales, at least for me, to also do deep flush triggering
through the same interface.
Return ENXIO or EOPNOTSUPP from the ioctl when it isn't supported?
