[Ocfs2-test-devel] [PATCH 27/59] reflink_stress_test: abort if truncate reflinked file fail

[Junxiao Bi]

From: Jeff Liu <jeff.liu at oracle.com>

Truncate a reflinked file might failed during stress testing, we have to abort in
this situation.  Otherwise, the test result should be wrong and confused the tester.
