Hi Josef, what about using your ioctl to exporting also other info ? For example devid, size, bytes, uuid ...
I know that btrfs filesystem-show does the same, but it reads the partition (the disk) instead of query the filesystem. That means: - It work even for unmounted filesystem (which is good) - The results are inaccurate for a mounted filesystem, because the read data is not valid until a flush of the pages (which is bad.. very bad). All the data are enclosed in the struct btrfs_device, so is very easy to extract. Regards G.Baroncelli On Tuesday, 28 September, 2010, Josef Bacik wrote: > This was a request from the systemd guys.
