Hi,
I found there are two new LTP changes have been applied, which would be
probably impact to your case:
commit aabb8340f63ed31afe995fd97795e542dc68b93c
Include usctest.h in test.h
commit 605fa3362fd7cef0baa2131be32cf44661783d3e
Get rid of TEST_CLEANUP
Seems we should remove two lines of the testcase as below otherwise it
can't be compile.
BTW, I tested it on patched kernel it can works well and Bug reproduced
with unpatched kernel.
Thanks,
Li Wang
