Apologies, I meant each of the native methods where the decision to use
direct I/O or not would be a lot more maintainable in Java. You'll see
that there are already code paths for direct vs. heap buffers.
Anyone else has other opinions on where is the best home for O_DIRECT flag? The
flags under jdk.unsupported will eventually be removed in the future JDK
release?
If we agree ExtendedOpenOpen is the best home for O_DIRECT, we can modify that
for sure.
I think ExtendedOpenOption is the right place. It's still TDB as to
whether to put these extensions but that should be transparent to anyone
using this when on the class path.
