Subject: [PATCH] multifd: Be consistente about using uint64_t
Date: Fri, 17 Jan 2020 14:56:39 +0100	[thread overview]
Message-ID: <20200117135639.14602-1-quintela@redhat.com> (raw)

We transmit ram_addr_t always as uint64_t.  Be consistent in its
use (on 64bit system, it is always uint64_t problem is 32bits).
