The bug was exposed only\nwhen compiling at -O0, probably because the compiler was padding variables at\nhigher optimization levels.\n\nThis patch fixes this problem by declaring user_interval as u64. This also\navoids wrap-around issues for large period on 32-bit systems.\n\nCommiter note:\n\nMade it use OPT_U64(user_interval) after implementing OPT_U64 in the\nprevious patch.\n\nCc: David S.
