From: "Dr. David Alan Gilbert" <dgilb...@redhat.com> Fix comparison of vmstate_info_int32_le so that it succeeds if loaded value is (l)ess than or (e)qual
When the comparison succeeds, assign the value loaded This is a change in behaviour but I think the original intent, since the idea is to check if the version/size of the thing you're loading is less than some limit, but you might well want to do something based on the actual version/size in the file Fix up comment and name text Signed-off-by: Dr. David Alan Gilbert <dgilb...@redhat.com> --- V2 Just missed the signed-off-by vmstate.c | 15 ++++++++------- 1 file changed, 8 insertions(+), 7 deletions(-) diff --git a/vmstate.c b/vmstate.c index 284b080..d1f5eb0 100644 --- a/vmstate.c +++ b/vmstate.c @@ -321,23 +321,24 @@ const VMStateInfo vmstate_info_int32_equal = { .put = put_int32, }; -/* 32 bit int.
