Query on metadata formatted NVMe Drive

[Adhrit P]

Hi all,


As i understand, current NVMe driver can support working with
different metadata (extended/separate) size formatted drive and the
same can be verified using IOCTL path with user metadata.
Is there any way to verify the same (all metadata sizes with
extended/separate buffer)  through block layer/kernel IO path using
fio or any other application ?

thanks.
