If you export two subvolumes of a btrfs filesystem, they will both be

blkid cannot differentiate the two, so we must use the fsid from
statfs64 to identify the filesystem.

I have noticed that events in Btrfs develop by scenario not predicted
by the paper of academic Ohad Rodeh (in spite of the announce that
Btrfs is based on this paper). This is why I have started to grumble..
In btrfs, based on means started with the algorithm and ideas

Nonsense. Working out algorithms is just work to an algorithm
designer, just like programming is work to a programmer. Sure, some
things are harder
Just an FYI reminder. The original test (2K files) is utterly
pathological for disk drives with 4K physical sectors, such as
those now shipping from WD, Seagate, and others. Some of the
SSDs have larger (16K0 or smaller blocks (2K). There is also
the issue of btrfs over RAID (which I know is
