The motivation for this series has two primary goals. We want to enable
support of multiple simultaneous messages and make the channel more
robust. The way it works right now, the driver can only send and receive
a single message at a time and if something goes really wrong, it can
lead to data corruption and strange bugs.
This works better than v3.
For the basic scenarios:

Sorry I'm reverting my tag.
After the series, the CP segfaults on each rmmod idpf:

Only restarting the CP helps -- restarting the imccp daemon makes it
immediately crash again.
This should be dropped from the next-queue until it's fixed.

I definitely tested rmmod so I'm frankly not understanding how this can
be possible. If you would like I'm happy to sync on how you're able to
cause this to happen. Our internal validation verified 1000 load/unloads
passed their testing.
Is there more you're doing other than just rmmod?
