Subject: ioctl: set data length when retrieving LBA status
X-Git-Tag: v1.7~10

ioctl: set data length when retrieving LBA status

Current nvme_get_lba_status() function does specify any data_len in the
admin command, resulting in zero data being returned.

This is the least intrusive change as it requires no update to nvme-cli.
