Chanages since v3:
- abort test-case instead of exiting if heap/mem allocation fails
- Correct test_alloc_zeroed() test case in case of failure
Changes since v2:
- Minor improvements in test_alloc_zeroed() results
Changes since v1:
- Update some more error handling code

Might as well setup goto out to clean up heap_fd, dmabuf_fd instead of these returns for the test functions, which leave a bunch of FDs open until the program exits. With those fixed: Reviewed-by: T.J. Mercier tjmercier@google.com Thanks!
