The idea was to make -util the general bag of bits just like
migration-helpers is currently.
-common should be the more "important" migration-specific functions,
code that we spend more time reading and that are actually responsible
for the results of the tests. Consider:
static void test_multifd_file_mapped_ram_fdset_dio(void)
{
...
if (!probe_o_direct_support(tmpfs)) { <--- just a helper
g_test_skip("Filesystem does not support O_DIRECT");
return;
}
test_file_common(&args, true); <--- actually doing the heavy-lifting
}
We could to some renaming and restructuring, but I think the distinction
is important. We already have it today, what is -common is all stuffed
into migration-test.c and the rest is in migration-helpers.c.
