Subject: uloop: add uloop_timeout_remaining64
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3344157381505e343b334e2eb6c60c9d3318e5bb;p=project%2Flibubox.git

uloop: add uloop_timeout_remaining64

This uses the same return type as tv_diff so we don't need to check for
integer overflow.
