3.5.0-rc6: btrfs and LVM snapshots -> wrong devicename in /proc/mounts
Hi,
using btrfs with LVM snapshots seems to be confusing /proc/mounts
After mounting a snapshot of an original filesystem, the devicename of the
original filesystem is overwritten with that of the snapshot in /proc/mounts.
Steps to reproduce:
arnd@kallisto:/mnt$ sudo mount /dev/vg0/original /mnt/original
[ 107.041432] device fsid 5c3e8ca2-da56-4ade-9fef-103a6a8a70c2 devid 1 transid 4
