Description


When accessing multiple RBD-Volumes from one VM in parallel, we are
receiving an assertion:

This is reproducible by doing the following inside a VM:

# mkfs.btrfs /dev/vdb /dev/vdc /dev/vdd /dev/vde
# mount /dev/vdb /mnt
# cd /mnt
# bonnie++ -u root -d /mnt -f

Any hints are welcome...
