Subject: [PATCH v4 06/15] exec: Drop "shared" parameter from ram_block_add()
Date: Thu,  5 Mar 2020 15:29:36 +0100	[thread overview]
Message-ID: <20200305142945.216465-7-david@redhat.com> (raw)
In-Reply-To: <20200305142945.216465-1-david@redhat.com>

Properly store it in the flags of the ram block instead (and the flag
even already exists and is used).

E.g., qemu_ram_is_shared() now properly succeeds on all ram blocks that are
actually shared.
