From 7a5de5512296fd2ab7a497e4a576196b1f046e78 Mon Sep 17 00:00:00 2001 From: Miroslav Lichvar Date: Tue, 13 Jun 2017 12:57:07 +0200 Subject: [PATCH] kselftests: timers: Fix inconsistency-check to not ignore first timestamp When the first timestamp in the list of clock readings was later than the second timestamp and all other timestamps were in order, the inconsistency was not reported because the index of the out-of-order timestamp was equal to the default value.
