From 4746a58f3b67abf5546243fcad04d2e07a668a14 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Fri, 22 Apr 2011 16:37:05 +0300 Subject: fs-tests: integck: add -e option to verify operations Improve the test and add -e option which forces integck to verify all operation it performs. This patch does not implement file writes and holes operations so far - will be done in subsequent patches.
