Hi, Aneesh,

After applying this patch series, several of my namespaces no longer
enumerate:

Before:

# ndctl list
[
  {
    "dev":"namespace0.2",
    "mode":"sector",
    "size":106541672960,
    "uuid":"ea1122b2-c219-424c-b09c-38a6e94a1042",
    "sector_size":512,
    "blockdev":"pmem0.2s"
  },
  {
    "dev":"namespace0.1",
    "mode":"fsdax",
    "map":"dev",
    "size":10567548928,
    "uuid":"68b6746f-481a-4ae6-80b5-71d62176606c",
    "sector_size":512,
    "align":4096,
    "blockdev":"pmem0.1"
  },
  {
    "dev":"namespace0.0",
    "mode":"fsdax",
    "map":"dev",
    "size":52850327552,
    "uuid":"6d3a0199-5d9a-4fed-830d-e25249b70571",
    "sector_size":512,
    "align":2097152,
    "blockdev":"pmem0"
  }
]

After:

# ndctl list
[
  {
    "dev":"namespace0.0",
    "mode":"fsdax",
    "map":"dev",
    "size":52850327552,
    "uuid":"6d3a0199-5d9a-4fed-830d-e25249b70571",
    "sector_size":512,
    "align":2097152,
    "blockdev":"pmem0"
  }
]

I won't have time to dig into it this week, but I wanted to mention it
before Dan merged these patches.

I'll follow up next week with more information.

Cheers,
Jeff
