So it should work for raw AFAICT. Dan said the BTT ones don't make sense
because the namespace relative offset is dynamic.
# ./ndctl/ndctl list -NM
[
{
"dev":"namespace5.0",
"mode":"raw",
"size":33554432,
"uuid":"bb3539dd-065c-41bd-8bcc-dc3bbc3317a5",
"badblocks":[
{
"offset":4,
"length":1
},
{
"offset":32768,
"length":8
},
{
"offset":65528,
"length":8
}
],
"blockdev":"pmem5"
},
