Peter Xu 579cedf430 migration: Unify and trace vmstate field_exists() checks ... For both save/load we actually share the logic on deciding whether a field should exist. Merge the checks into a helper and use it for both save and load. When doing so, add documentations and reformat the code to make it much easier to read. The real benefit here (besides code cleanups) is we add a trace-point for this; this is a known spot where we can easily break migration compatibilities between binaries, and this trace point will be critical for us to identify such issues. For example, this will be handy when debugging things like: https://gitlab.com/qemu-project/qemu/-/issues/932 Reviewed-by: Fabiano Rosas <farosas@suse.de> Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Peter Xu <peterx@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com> Message-ID: <20230906204722.514474-1-peterx@redhat.com>		2023-10-04 13:19:47 +02:00
