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.
