Stupid me, I completely forgot that you can run multidisk arrays with
just block level partitions, just like with md raid! It will introduce
a rather significant management overhead in my case though, as
managing several individual partitions per drive is quite annoying
with so many drives.

First two patches are trivial cleanups that I've spotted while reading send.c,
can be applied independently.
The third patch contains the important bits, safety checks that the subvolumes
involved in send do not accidentally lose the RO status. I haven't seen this
documented anywhere that this is
All the subvolues that are involved in send must be read-only during the
whole operation. The ioctl SUBVOL_SETFLAGS could be used to change the
status to read-write and the result of send stream is undefined if the
data change unexpectedly.
Fix that by adding a refcount for all involved roots and

No problem. You have to wait a bit though, as the volume is currently
going through a reduction in the number of drives from 8 to 7 and I do
not feel comfortable stalling the volume while that is happening. I
will report back with the logs later on.
