Subject: [PATCH 17/20] lightnvm: define chunk states
Date: Wed, 21 Feb 2018 10:26:55 +0100	[thread overview]
Message-ID: <1519205218-26994-18-git-send-email-javier@cnexlabs.com> (raw)
In-Reply-To: <1519205218-26994-1-git-send-email-javier@cnexlabs.com>

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. This state is transparent for the device.
