Chris / list,
stat(2) seems to return invalid major/minor device info
for btrfs filesystems.
Why? Is this a bug?
This is not invalid and not a bug. It's a superblock without a device,
and expected behavior.
There is no one-to-one relation from a btrfs mountpoint to a device,
it's a tree, and therefore therefore there can not be a single
major/minor.

Sure there is for the most common case.
When there is only a single device, stat() should return that device.
When there are several, it should do something different.
But really, it should be using DM/LVM when there are multiple devices.
