TREE_SEARCH ioctl doesn't help in this case
the dev item don't provide all the info
that btrfs-progs might need in the long run
(and even the current needs).
Thanks, Anand

1) Have a simple single fixed input structure for each ioctl. Maybe
with some extra padding and a flags argument if you think stuff is going
to be added over time. No generic header. No casting. The ioctl
number defines the input structure. If you need a different structure
later, use a
This adds two ioctl BTRFS_IOC_GET_FSIDS and BTRFS_IOC_GET_DEVS
which reads the btrfs_fs_devices and btrfs_device structure
from the kernel respectively.
The information in these structure are useful to report the
device/fs information in line with the kernel operations and
thus immediately

Why not just use sysfs to export the device lists?
