[PATCH 17/20] lightnvm: define chunk states

Define chunk states as given in the 2.0 spec. Also, add an extra chunk state that signals that the chunk is in use by the host. This allows for the chunk metadata to be "owned" by a target when active, thus completing the chunk state machine from the host perspective and facilitating sanity checks.

[PATCH 14/20] lightnvm: make address conversions depend on generic device

On address conversions, use the generic device, instead of the target device. This allows to use conversions outside of the target's realm. Signed-off-by: Javier González --- drivers/lightnvm/core.c | 4 ++-- include/linux/lightnvm.h | 8 2 files changed, 6 insertions(+), 6 deletions(-
