From 6cd92a8216afcd1d3f6ff90cc150ba150800b11d Mon Sep 17 00:00:00 2001 From: Guillem Jover Date: Aug 22 2019 18:04:21 +0000 Subject: harness: Print better error messages on error conditions in 22.t These should help diagnose problems when dealing with error failures. In particular this helped distinguish the problem with io_pgetevents() not being implemented and it failing due to the sigset_t layout bug.
