From b69c99463d414cc263411462d52f25205657e9af Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Fri, 24 Sep 2021 12:04:27 +0200 Subject: [PATCH] selftests: net: fib_nexthops: Wait before checking reported idle time The purpose of this test is to verify that after a short activity passes, the reported time is reasonable: not zero (which could be reported by mistake), and not something outrageous (which would be indicative of an issue in used units). However, the idle time is reported in units of clock_t, or hundredths of second. If the initial sequence of commands is very quick, it is possible that the idle time is reported as just flat-out zero. When this test was recently enabled in our nightly regression, we started seeing spurious failures for exactly this reason. Therefore buffer the delay leading up to the test with a sleep, to make sure there is no legitimate way of reporting 0. Signed-off-by: Petr Machata Signed-off-by: David S.
