I’d like to back port this fix for DirectIOTest. The test is failed on FS with r/w blocks larger than 4k. 

The fix doesn’t apply cleanly due to missed "8244224: Implementation of JEP 381: Remove the Solaris and SPARC Ports”. Manual modification is required for
- copyright year
-  isDirectIOSupportedByFS remains in the code

Related backport of JDK-8265231is not required since no public functions are affected.
