It should be enough to run a zdtm test-suit to check that change does not break something for CRIU (will do).
jfyi: checked 0cc53520e68 with patch "[PATCH] use uniform permission checks for all mount propagation changes" (+ s/from/to/), there is no problem on criu-zdtm mount related tests. I see some problems on socket related tests on it, but it looks unrelated.
