OK, my only concern is: Heinz, should you have used
dm_bufio_discard_buffers() in dm-ebs commit a5089a95d84c ("dm ebs: pass
discards down to underlying device")? Or are you certain all ebs'
bufio buffers have made it to disk?
Also now seeing that the FIXME commit a5089a95d84c removed referred to
making use of dm_bufio_discard_buffers()...
