Subject: [PATCH v1 16/29] virtio-mem: memory block states are specific to Sub Block Mode (SBM)
Date: Mon, 12 Oct 2020 14:53:10 +0200 [thread overview]
Message-ID: <20201012125323.17509-17-david@redhat.com> (raw)
In-Reply-To: <20201012125323.17509-1-david@redhat.com>
let's use a new "sbm" sub-struct to hold SBM-specific state and rename +
move applicable definitions, frunctions, and variables (related to
memory block states).
While at it:
- Drop the "_STATE" part from memory block states
- Rename "nb_mb_state" to "mb_count"
- "set_mb_state" / "get_mb_state" vs. "mb_set_state" / "mb_get_state"
- Don't use lengthy "enum virtio_mem_smb_mb_state", simply use "uint8_t"
