Description

While running sanity test 180c with default local configuration (OSTSIZE=200000), it failed as follows:

== sanity test 180c: test huge bulk I/O size on obdfilter, don't LASSERT == 01:03:30 (1383033810)

ERROR: Module obdecho is in use
 sanity test_180c: @@@@@@ FAIL: test_180c failed with 4

We need fix obdecho_test() to calculate write count instead of hard-coding it with 10. I'll upload a patch.
