From 4c83349e5a1724ebe21a024c06b5e0b409d31ef3 Mon Sep 17 00:00:00 2001 From: Alberto Bertogli Date: Fri, 3 Jul 2009 22:27:50 -0300 Subject: [PATCH 06/74] tests/stress: When using libfiu's POSIX wrapper, inject more failures With this patch it is possible to run the stress test using libfiu's POSIX preload library to simulate failures in the POSIX functions, and see how libjio copes with it.
