Right, a recent Josef Bacik's patch[1] changes how the device name is
computated. This explains why on a 3.4.4
kernel I was not able to reproduce the bug. Anyway the problem is not in the
Bacik's patch
but in the fact that btrfs allow to replace an already mounted device. I am
working on a patch which doesn't allow that.
