[PATCH v4 0/2]ndctl/namespace: Fix and improve write-infoblock

[Tarun Sahu <tsahu@linux.ibm.com>]

This series resolves some issues with write-infoblock 
command and provide support to write-infoblock for sector 
mode namespace

write-infoblock command has issues regarding updating the 
align, uuid, parent_uuid. In case of no parameter passed 
for it, this command used to overwrite the existing values 
with defaults.

In PATCH 1/2 these parameters will be set to their original 
values, incase, values hasn't been passed in command 
arguments

write-infoblock command doesn't have support for sector/BTT 
mode namespaces. They can be converted to fsdax, but can 
not be written being in sector mode.

In PATCH 2/2, It creates a functionality which write 
infoblock of Sector/BTT namespace. Currently only uuid, 
parent_uuid can be updated. In future, Support for other 
parameters can easily be integrated in the
functionality.
