SubjectRe: [PATCH] Allow cross subvolume reflinks (2nd attempt)

Thanks for working on that. What happens if two subvolumes of the same
filesystem are mounted on two different places ?

I usually do:
mount -o subvol=__active /dev/sdX /
mount -o subvol=. /dev/sdX /var/btrfs

So two different subvolumes of the same filesystem (the one on /dev/sdX)
are mounted on two different places.

Is it possible to do
cp --reflink /tmp/foo /var/btrfs/tmp/foo2

Thanks
