+# FSQA Test No. 068
#
-# Test Linux LVM snapshot creation
-#
-# The timing and placement of kills and waits is particularily sensitive.
-# Don't change them unless you want to spend some time getting it right again.
+# Test case to reproduce xfs_freeze hang under filsystem load.
+# The fail case for this test is a hang on an xfs_freeze.
