Hi Arnd,
I am trying to reproduce this bug. Which kernel version are you using ?
I'm using linus' vanilla tree from Sunday which is 3.5.0-rc6 plus some unsuspicious commits.
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.
