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.
