[11u] RFR 8265231: (fc) ReadDirect and WriteDirect tests fail after fix for JDK-8264821

[Sergey Nazarkin]

Hi Paul,

Pardon me for the intrusion and I’m definitely not a reviewer,  but according to original bug isDirectIOSupportedByFS is required for tests running on Solaris.  As I’m author of the 8264821 jdk11u backport, I’d like to clarify, for my further activity, should I care about Solaris platform when patches is taken from jdk17?

Sergey
