In any case this looks safe to me as i is an unsigned int while MAX_MON_DOMAIN is 64 (also an unsigned int, I believe). And the code being replaced appears to be a min() operation in both form and function.

When calculating size of own domain based on number of peers, the result should be less than MAX_MON_DOMAIN, so using min() here is very semantic. Signed-off-by: Li Zetao <lizetao1@huawei.com> --- net/tipc/monitor.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
