[PATCH libnbd 4/4] lib: Atomically update h->state when leaving the locked region.
...te = the state on entry to the locked region
- h->next_state = the current state and what the "publicly visible"
state will become when we leave the locked region
Some calls to get_state become calls to get_next_state depending on
which of these they are trying to read. Calls to set_state become
set_next_state because that is what gets updated.
When we leave the locked region we update h->state.
The purpose of this patch is to make it easier to reason about the
state in lockless code.

[PATCH libnbd v2] lib: Atomically update h->state when leaving the locked region.
...to move
atomically from its previous state to the final state without going
through any intermediate states.
Some calls to ‘get_state’ become calls to ‘get_next_state’ if the need
the real state. Others which need to see the publicly visible state
are changed to ‘get_public_state’.
All calls to ‘set_state’ become ‘set_next_state’ because that is the
real state that gets updated.
The purpose of this patch is to make it easier to reason about the
state in lockless code.

For some volume it works, but for others i can't enable geo-replication and have this error with a faulty status:

[PATCH] drm/nouveau: suspend to D3hot, not to D3cold
In the autumn and winter it's considered bad form to set power state to D3cold, it might
cause the device to freeze to death. This is also the case in the other seasons, so any
device in the southern hemisphere is affected too.
D3cold is not a valid state in a call to pci_set_power_state, only up to D3hot is allowed.
